I don't like crowds of people in general. When they're all talking at the same time, and making noise. Crowds are the worst ... All the lights and the shouting and the people. It's like broken glass in my head.
There are roughly one-sh*t billion tropes so PLEASE look through them before adding one. Otherwise add what you like. ADDITION: PLEASE read through the trope description provided before submitting something. It's not a huge deal but too often people submit characters that don't fit just because they misinterpreted the title...
