Whose birthday is it tomorrow?

M: Hi, Linda.
W: Hi, James. What are you doing in the mall? You said you avoid these places and here you are.
M: Oh, I still do but it’s my roommate’s birthday tomorrow and I am looking to get him a present.
W: Have you any idea what to get?
M: Not really. I want to get him something he will be able to use instead of something he’ll just shove into the closet.
W: That’s true. I know half the time I get something from somebody I hardly ever use.
M: I know, I know. That’s the problem. That’s why I hate buying gifts for somebody because it can never be perfect. So, I am heading over to the clothing store right now.
W: Perhaps you are trying too hard to get something very impressive or decorative. I always think a gift should be practical. Why don’t you think of something he might like or something that he will most likely get soon?
M: Oh, I know. His rucksack is almost wrecked. Maybe I should get him a rucksack instead.
W: That sounds like a perfect gift.
M: Gosh, now I am wondering which color I should pick. He is really picky about the color.
W: That’s not difficult. What was the last color he chose? He obviously chose it for a reason.
