This isn’t my real account due to the fact I don’t really want this linking back to me. I (16F) recently got into an argument with my mum about how I treat my brother (25M). I make sure to avoid him because he quite frankly makes me uncomfortable. I can’t even have friends over because he follows them around the house looking at their behind. There has also been multiple times where he has known i’m in the restroom but yet still comes into the restroom when there’s 3 other toilets in the house? Not to mention when I was in elementary school I was taking a shower and turned around to see my brother looking at me while he was holding the shower curtain open. In that moment I was in shock and he promptly ran out of the bathroom inferring he knew what he was doing was wrong. Though my mum knows all about this she still expects me to take care of my brother when my dad and her get too old, but quite frankly I KNOW I can’t. He urinates and poops himself when he doesn’t get his way, and I know i can’t handle that. He also used to attack me when I was younger so if I were to take care of him and want to have a child myself I don’t know if I’ll be able to trust him. So AITA?
