I sure do... It's fun to tease her, like when I make embarassing videos about her and unplugging the cable modem... It's fun to hear her scream! I also have a half sister. I've barely met her.
Sadly, my brother was a miscarriage. It was before I was born.
Heh, only an annoying older brother. xD Hes 15 and I'm 11, and usually all he does is play videogames. I don't mind though...more computer time for me! We both argue alot and we hit eachother (not very hard, just a light slap on the arm or leg). But I love him. xP
