You know you're a BHM when you're eating out with people and someone asks "Does anyone want this" then looks directly at you.
You know you're a BHM when you order a bunch of food for a meal at a restaurant and the waitress says "I bet your parents get scared when you come home"
(That last one actually happened to me...at the time I was in high school, not in college, but the waitress assumed I was in college, and it was during a winter break, so she thought I was visiting home...those were her exact words to me)
You know you're a BHM when you go to a buffet alone and the waitress brings you 5 extra plates (instead of the customary 1 or 2) and says "looks like you'll be needing these" (again, happened to me).
You know you're a BHM when the waitress gets that annoyed look on her face when you walk in (because to her, you'll order a lot of food making more work for her)
You know you're a BHM when you get stuck in desks at school (check)
You know you're a BHM when you run out of breath just walking up some stairs (happens to me)
You know you're a BHM when you're at a party and realize you can't come and go as you please without knocking things or people over.
