My stepdad just eats/drinks my daughter and I's stuff without even asking like a fricking kid and it's annoying like just ask. And add in the fact that he has means to get his own stuff. Also the fact that he acts like it's so annoying whenever my daughter wants something he has. But can drink up her juice and eat her food with no problem. At least she asks and says please and thank you. He just takes without asking. I'm constantly having to hide stuff from him or just go without. So much food disappears and I just can't afford for this to keep happening.
