You know, considering you've had both a beer incident and a bong incident today--and considering the fact that you're still young and living in her house and under her rules--it sounds like you got off lucky. It also sounds like it might be understandable if she's in a bit of a bad mood. Sometimes it's wise to give moms a wide berth around holiday time and to watch your step. (I learned this from dealing with my own mom, to be honest. The holidays always put her on edge.)
