My cousins coming to to visit, uh-oh, help!?

I have a little brother, there are times when I just don't like him. Ive had the same feelings that you have had or are having. Just accompany him with HIS interests. I also recommend taking your cat to the veterinarian if it starts having health problems. Little kids love talking so just sit and listen, and about him pushing you of whatever he did. His condition could contribute to him getting aggressive. If you want to bring your friend along with you just make sure you dont push your little cousin out of your activities, taht will cause him to act out and cause more frustration to you.
