My mom still will announce when she's gone to the bathroom, and it can be disturbing. (For instance, if she comes out of the bathroom, and you ask her how she feels be prepared to hear, "OHHHH, it was like a cork! It just came out ... " Yeah, no one wants to hear about that.
Another thing she does, lately, is to sing loudly and off-pitch. Tonight I repeatedly asked her to stop, as it was hurting my ears. Before that, she kept shouting, even though she was standing in the kitchen and I was in the dining room (which is right next to it). I honestly don't think she realises how loud and abrasive she can be until I tell her to can it.
