The drive home remained almost silent. Rachel held the cake on her lap as though it contained something breakable, while Lucas watched the passing streetlights through his window. He did not ask why we had left, and he did not mention the giant dollhouse or the pink balloons. His reflection looked older than seven, which frightened me more than an angry outburst would have done.

Mia remained unaware of the tension, humming softly while swinging her feet against the back seat. I envied her innocence because she still believed every grandparent behaved with the same warmth she received from us.

At home, the decorations we had prepared that morning still filled the living room. Blue dinosaur balloons floated beside the staircase, and a banner reading “Happy Seventh Birthday, Lucas” stretched above the dining table. The party favors remained arranged in a corner, and the plates were already set for guests who would never arrive from my parents’ house.

I placed the cake on the table and turned toward Lucas.

“I am sorry, son,” I told him. “Today did not happen the way we planned.”

He set his toy cars on the floor and nodded carefully.

“It is okay, Dad,” he said. “Maybe Grandma and Grandpa just forgot.”

Rachel knelt beside him, and her voice became gentle without losing its firmness.

“They did not forget, sweetheart. They made a choice, and their choice was unfair.”

Lucas looked between us.

“But they still love me, right?”

The question broke whatever defense I had built around my parents. I realized that I had spent years protecting their image while allowing Lucas to question his own worth.

I called two of his classmates, and fortunately their parents were available to bring them over that afternoon. We served cupcakes, played a dinosaur-tail game, and organized a foam-dart battle in the backyard. For a while, Lucas laughed with genuine excitement, although his happiness returned cautiously, as though he feared someone might take it away again.

That evening, after both children were asleep, Rachel closed the living-room door and faced me with exhausted determination.

“We are finished pretending that their behavior is normal,” she said.

I sat quietly because I knew she was right. Still, a small part of me hoped that the situation had been an unfortunate misunderstanding rather than a deliberate decision.

The messages that arrived the next morning destroyed that hope.

Brooke wrote, “What was wrong with you yesterday? Mom has been crying because you embarrassed everyone.”

I answered, “You and Mom erased Lucas’s birthday so your children could have another party.”

She replied, “Nobody erased anything. Combining celebrations was simply practical, so please stop acting offended.”

I stared at the message for several minutes before writing, “Your idea of practical behavior made a seven-year-old believe he was invisible.”

My mother called that evening, and I nearly ignored her before deciding that avoidance would only prolong the conversation.

“Ethan, you reacted far too strongly,” she said. “Brooke has been dealing with difficult circumstances, and her children need additional support.”

“When will Lucas receive support from you?” I asked. “When will he receive the same attention you give Brooke’s children?”

She paused, then repeated the sentence I had heard throughout my childhood.

“He is young, so he will forget this very soon.”

I laughed once, although nothing about the situation was funny.

“I still remember my eighth birthday, Mom. You canceled my party because Brooke had the flu, and you promised to arrange another celebration that never happened.”

Silence filled the phone line.

“You should stop carrying resentment,” she finally said. “It is unhealthy.”

“Then perhaps you should stop giving me new reasons to carry it,” I answered before ending the call.

Part 4: The Empty Chairs

Several weeks later, Lucas prepared a science-and-art exhibition at school. He created a plaster volcano with red paint flowing down its sides, and he spent evenings explaining how the eruption mechanism worked. Each student could invite four guests, so Lucas selected Rachel, me, and his grandparents.

When he handed me the invitation, I asked whether he genuinely wanted my parents to attend.

“They will come this time,” he said confidently. “I want to show them my volcano.”

Rachel sent my mother a reminder message explaining the date, time, and school address. The response arrived several hours later.

“We will see whether we can make it,” my mother wrote.

That phrase had appeared whenever I asked whether she would attend an important event in my life. She had used it before my college graduation, and she had not appeared then either.

On the evening of the exhibition, Lucas stood beside his volcano wearing a paper name tag and a nervous smile. Rachel and I applauded every presentation, while families crowded around the tables and asked questions about the children’s projects. The seats reserved for my parents remained empty until the school closed.

Lucas watched the doorway repeatedly, holding his project description in both hands. When the teacher announced that the event had ended, he folded the paper carefully and placed it inside his backpack.

On the drive home, he remained silent until we reached our neighborhood.

“Did Grandma and Grandpa forget again?” he asked.
