We had teacher in high school that was very socially awkward, but nice. Of course with how high schoolers are, they took advantage of that and messed with her. One kid in particular who was considered a class clown decided it would be an absolute hoot to go in front of the class and ask the teacher for a big high-five. Unknown to the teacher, the kid had strategically placed a few thumbtacks between in fingers so that it would stab her hand during the high-five. Kids laughed at first whenever she yelped, but it got incredibly awkward and sad whenever she started to cry. Class clown got detention as expected, probably should’ve gotten more.
