Birthday present ideas?

My boyfriends 21st birthday is in TWO days, and I have no idea what to do for it. I'm 19 and currently unemployed, we both live separately with our parents. I know he's really excited about being able to buy alcohol, but I can't really do anything with that personally for him because I'm younger. He isn't allowed to come hangout by my house because, well to put it simply I'm not allowed to have anyone over besides my bestfriend. And anything by his house would be up to him and his schedule due to his step dad. He isn't an especially social person.
