Say you have a big butt and you want some ice cream. You go into an ice cream shop - the clerk gives you that "fat pig wants her fix" look. Maybe he takes the thin, buxom woman who came in after you first, ignoring you.
Do you:
A - Walk out of the shop, go home and cut yourself to figurative (or literal) ribbons?
B - Walk out of the shop, go home and order in?
C - Loudly say "Excuse me - I was next" , order what you want and eat it there?
I used to be an A person. It used to be that what a stranger thought of my eating habits could mess me up for a week. Now I'm mostly a C person. It fucks me up, but I don't show it. I assert my place in the line, order my ice cream and take it home with me . . . where I eat it while feeling like a lowly piece of shit.
