Random memory, came up while chatting with kennapea:
Back in high school, I was waiting in the office for some reason to talk to someone or such, and was rifling through the pamphlets they had available there out of boredom. One of them was "How to cope with the loss of a child". I found this hilariously morbid to be available there, so I took one to read later and stuffed it in a coat pocket.
Days later, some kid I barely knew kept talking at me and being generally annoying. So I turned to him and calmly interrupted him, "Hey, could you give this to your parents before tomorrow?" and pulled the pamphlet out and handed it to him.
The look on his face was priceless: You could see him wondering why the HELL I had one of those just sitting ready in my pocket. He just stopped talking, and walked away.
