The House on Mango Street
Someday I will have a best friend all my own. One I can tell my secrets to. One who will understand my jokes without my having to explain them. Until then I am a red balloon, a balloon tied to an anchor. (3.4)
You want a friend, she says. Okay, I'll be your friend. But only till next Tuesday. (4.3)
If you give me five dollars I will be your friend forever. That's what the little one tells me.
Five dollars is cheap since I don't have any friends except Cathy who is only my friend till Tuesday. (6.1)
