Kids cause (very) thick skin

I work with kids of all ages at camp and for the past few months I've also been working at a local elementary school as a recess monitor. I absolutely loving it at this school and the kids never sees to amaze me with their pure curiosity and lack of tact. They are the only beings that see and ask things as they are with no dancing around a subject nor regard on how things may sound.

Regards to my hair:
I have short hair, very, very short hair and boy have I become very confident in myself. Each afternoon, sometimes more, I'm asked the same question, "Are you a girl or a boy?"

Regards to my watch:
I go through watches at a ridiculous pace no matter what fancy brand I buy. After my last two watches killed over I decided to go to Meijer and purchase a cheap watch. The latest comment is, "Hey, that's the same watch (insert name) has!"

Regards to my size:
I'm not even sure why or how this came up but boy was this kid's substitute teacher furious he asked, "What size shoe do you wear?" I personally thought it was funny and wanted to hear why he wanted to know.

Have you had any hilarious, embarrassing or weird questions or comments from kids? Feel free to share your moments below.
