A: Ugh. I just don't know what to get you for your birthday. You never hung up the self portrait I make you from the string and stuff I collected from the streets, and you didn't like my home-brewed mouthwash either. I know, you pretended to like it, but you poured it down the drain as soon as I left. And my homemade cornflake-covered pineapple lasagna wasn't a hit with you either. I just don't know what to get you.
B: Erm, uh... you could get me a book. I like books.
