So my mom is here for a few days which already had annoyed as it is, and she gets here and has my brother with her! The same brother who screamed at my child. Nowhere in any conversation was I asked if it was ok for him to come, nor was it even mentioned that it was even a possibility. I’m beyond mad and I don’t even know what to do. I literally want to leave my own house right now.
