I don't understand it when a person has bad manners when he is a guest in someone's house. I know whenever I am at a friend's house and we have a case of the drunchies I always clean up after myself. Put the dishes in the dishwasher, put the food away, etc. And I don't eat all their food. Usually. Most times when I have people over, which I do quite frequently, I have to clean up after everyone leaves. That's fine; it comes with the territory. I usually get help collecting beer cans and bottles, which is a very nice guest-ure. However, today when my dad got home he made a strange discovery and asked me if anyone I had over last night was crazy. I think he meant certifiably as opposed to the kind of crazy I am because someone decided to go into my pantry and smell or taste all the jars of peanut butter, jam, sauce and things of the like. Unopened or opened - didn't matter to this guy. And all the tops were off! It was like freakin' Mardi Gras for non-perishables in there. Who does that?!
It is important to be a good guest. It is also important not to be a freaking weirdo and remove the lids from multiple jars of food for no good reason. There is no good reason for doing that. It's weird. Especially if it's not even your house.
