boy help!

okay ladies. this friday i have a boy come over. he's just a friend and i've had plenty of friend boys over before. i'm only 15 so obviously i'm still at home with my parents. what are some things we can do other than just sit there and watch tv? my 9 month old nephew lives here with me so i was hoping that could make things a little less awkward. i don't want him to feel uncomfortable or bored. what can i do?
