Why did my teacher think this was weird?

Today in our cl, we got back our paper on where we wanna be in 10 years. I put I wanna play pro baseball cuz Im good at baseball and Im gonna play in college. I put that Im gonna have my sister be my agent cuz she's gonna go to Princeton Law School and most agents are also lawyers and that I could pay her cheaper since she's my sister. I also said that she could flirt with the owner of the team since she's kinda pretty and guys have crushes on her. My teacher underlined that and thought it was kinda weird that I would have my sister be by agent instead of hiring a guy who has a lot of other players and who has experience. Why did my teacher think that it was weird that I would hire my twin sister as my agent??
