I'm torn, girls. My sister has a denim dress that I love even though it doesn't quite fit me properly. She has decided that she's selling it at the garage sale my family is going to have next week. Now I want it, and I can't just ask her for it because she doesn't know about me (yet). Since she plans on selling it (instead of just giving it away) I would feel wrong just taking it while she's not around, and I also think she might notice if it went missing. Taking it isn't an option, asking her for it isn't an option, and yet I don't want to see it go. What should I do?
