Hm.. Not really embarrassing, but mine is more... Uncomfortable..
I ended up being stuck on the very end of the lunch table, sitting next to a boy who was known for crushing on all the girls. So I scoot all the way to the end, as far away from him as possible. We talk, he tells me I look lonely.. Then he starts SINGING to me. X_X I think the entire lunchtable heard.. He sang something like "Mr. Lonely" except the words were: Lonely, You look so Lonely... I was glad when lunch was over... XD
Now, this was both Embarrassing and Uncomfortable... And it was also at lunch.
On the second day of school, both my friends are cold lunch, so I end up sitting by a boy who was at the time an aqquantance. We joke around a lot. So he's bugging me, and I tell him I'll 'kill' him at recess. Then he says something like 'Oh yeah?' and picks up his supposedly empty applejuice carton. I tell him he'd better not, and he does anyway. He holds it upside down over my head, and guess what? It wasn't totally empty. Applejuice all over my head. (Right across from us sat the 'jocks', who laughed like crazy when it happened because they were watching.) I ended up having a sticky head the rest of the day because they couldn't do anything to let me watch it out. Joy. XD We're pretty good friends now, I understood he didn't know it still had applejuice in it, he knew I wasn't going to do anything to him at recess except give him the evil eye, so... Yup. lol
