I need to know what he likes.
Why do you want to know?
I would like to know what he loves to make sure that I'll buy the gift he really wants.
It is great that you are putting thought into the gift you are getting him. Asking his close friends about what he likes could be a really good way to get some ideas!
That's a good plan. I'm sure they can help!
I bet his friends can offer some great insight into what he is interested in so you can find just the right gift for him. Getting advice from people who know him is a good way to start brainstorming. You seem like a very thoughtful person so I am sure he will appreciate the gift you get for him!
