when your ears decide to boycott hearing and you have to make someone repeat whatever they said so much that it becomes socially unacceptable to say "what?" again and you're forced to just pretend you heard them and laugh and nod
There are too many bad feelings to count. To mention a few, presenting something you know won't work, running around a ton even when you're sick, having people "whisper" behind your back so loudly that you can tell they're talking about you, not talking to anybody for weeks, and i think i'll just stop there.
