rude

Man oh man, it sounds like this woman's boyfriend is trying way too hard. The dude went out of his way to give his girlfriend trouble for simply ordering what she was feeling like at a restaurant. I also might add here, that mac and cheese is generally universally adored. Sounds like this dude seriously needs to get his priorities in check. 

It's not that hard to be a decent houseguest. All you have to do is sit there and not punch holes in the wall. And even if you do punch a hole in the wall, there are ways to apologize and repay your host. Apparently that's too hard for some houseguests who do unforgivably disrespectful things.
