It depends.....some people I have an arrangement with and have said before "if you ever need blah blah blah go ahead". Like when my friend and her boyfriend had been fighting constantly, I told her she could come to my house whenever whether I was there for not.
But my sister, I still knock at her house. The only place I really don't bother with any of those niceties are at my moms house. Everywhere else I ask or wait for someone to tell me its okay. I think that stuff is pretty rude. And even though I would never reject someone from going in my fridge, it would still bother me if they just did it without asking. Its the principal I guess.
