I get bad vibes from excessively abstemious women. You don't have to shovel it in with a forklift, but don't herd one tenth of your food around on the plate and then announce you're full. Either you're mentally ill or you think I'm a fool.
These women annoy me too. They don't just do it on dates, they do it with other women... it's almost like a competition on who can eat the least. On a date I eat what I normally would eat on any other occassion... a guy has to see what I'm really like.
