soooo my grandma has went crazy. at my sisters sons 2nd birthday party she went stupid and went off on my brother in laws dad because his gf kissed my nephew in the mouth. she did it in front of everyone and embarassed us so bad. then afterwards my sister told her she shouldn't of did that and it was really rude. my grandma got angry and started screaming at her. and before all that I was putting my daughter in a high chair and she gets up to come snatch her from me and do it herself and I said "no, I got it. I don't need help". she got angry about that and is not refusing to come around my sister and i. like wtf? all I know is she better think long and hard before she does this crap because I'm not allowing someone get my child used to them and disappear just because they have their butt on their shoulders and then reappear when they feel like it. I'm not playing that game.
