I have longish hair (usually tied up) and I do not hide my boobs under baggy clothing and/or sports bras.

That is what makes the events of last night so funny. I was wearing (unisex)flip flops, (mens) cargo shorts and a (womens) blue polo shirt with stripes. The usher at the movie theater called me sir! Here is a conversation I had with my girlfriend.

Me: Some guy just called me sir!
Girlfriend: What? How could anyone mistake you for a guy?
Me: I don't know!
Girlfriend: Man...even when you were in full drag I was like "Aww. She's so pretty!"

Hee hee hee!
