Absolutely anything that interests you.

Your boyfriend will think that just about anything you say is cute, but tell him how much you love him and how lucky you think you are to have him.
Some people may find it hard to get a boyfriend in high school, while others do not think it difficult.

Pop corn, lettuce, chips Your juices!
If that's the type of things he likes.
Ask him how his day is going, or what he did today. Just keep the conversation rolling, ask him questions about his hobbies, family, likes and dislikes. Share whats on your mind with him, or even if you have been together for a while and have a strong relationship, tell him how much you love him. Or play the questions and answers game. Be funny or say random things, crack some jokes.
give him anything you feel might be useful to him. Or anything that will help solve his problem.
If you don't try and get every nickel and dime from him he may be more willing to pay for some things. He's your boyfriend, not a piggy bank. Don't ask him to pay for unnecessary thing. Try paying for some stuff too, that will make things go a bit better.
