Student 1: Happy birthday!
Me: It's not my birthday.
Student 2: It's your birthday?!
Me: No, it's not my birthday.
Student 3: OMG, happy birthday!
Me: It's not my birthday. We're going to start the warm up in 3...2...1...
Whole class: HAPPY BIRTHDAY, TO YOU! HAPPY BIRTHDAY, TO YOU!

Slightly nervous to see what happens next week when it actually IS my birthday. I kid you not, all day random kids I didn't even know were coming up to me and wishing me happy birthday. Then they'd laugh and run away. I kind of felt like I was teaching 8 year olds instead of 8th graders. It was cute, in a really strange way.
