Rant! Anybody else have ungrateful ass siblings? My mom just came home from the hospital a few days ago. Today her tongue is swollen. She needs someone to sleep in her room to keep an eye on her. I asked my brother to do it. He says "I don't want to why can't you do it?" Seeing as I'm dealing with a super grumpy teething baby I can't sleep on no one's floor. He says "So! I don't want to sleep on her floor" After this I'm so done with him. I don't even know what to think right now! !! Now I'll get absolutely no sleep which is much needed right now!! ugh. Someone talk to me please?
