I am not so welcoming to my new "brother"

Well it has been awhile since I had my hooman write a story. She has been busy and I have been grumpy. I have a new "brother" I have known him since I was little. His mom had to go into a new place (she is very ick). She asked my mom if she would take care of Sylvester AKA TJ. Tj has known my mom since he was a kitten and would sneak over to her place to get the nip. I have never liked him as he kind of teased me alot when I was little. I also like being the only cat. Well he and I do not spend time together in the house or outside. He gets the front half of the house and I get to sleep with my mom. I am trying to tolerate him but IT IS SO HARD. May be one day I will not try to attack him. He does not attack me. Rainy here: TJ and Little Girl came from the same abusive household. TJ aka Syvester was adopted by a neighbor and has been with her for over 8 years. When she got sick, she asked if I would take TJ in since he knew me and my house. I knew Little Girl had issues with him. But, I think it may take a year or so for her to not be so aggressive (more from her growing up issues in an abusive house) So far it has been working out.
