He remembered promising his father he would deliver a heartfelt speech, but the words seemed to have vanished. All that remained was a hazy fog in his brain. The catered chicken smelled delicious, but he had no appetite. He wished he could just close his eyes for a moment.

He watched the other guests milling around, their animated chatter grating on his ears. Everything felt loud and distant. It would be a while before his turn came. Just a little while.
