My partner works at a library, and some kids at a high school did a walkout protest. They came to the library and sent two kids in to politely ask if the group could use the bathroom there. Before the kids could all filter in and finish they got a call from the headquarters branch that "protests aren't allowed on library property". No one passed this message along to the kids 
Edit: some cops were following the kids around, they hadn't messed with them at the time my partner talked to them (they asked) but I still wonder what they were up to.

When I was 18, I visited a hairdresser to get a nice cut for prom, I was a boy at the time. She told me my hair wouldn't make it to 30. She was right
