Ask him questions about his interests. “You’re into baseball, right? Did you see the game last night?” “Are you still fixing up that car with your dad? How’s that going?” Get excited about things you have in common. “Have you gotten the new Call of Duty yet? It’s so awesome. We’ve gotta try it together sometime.” “That new horror movie that’s out is so good. You’ve gotta watch it.” Joke around with him and make fun of him in a friendly way. “No way are you the best one on the team! I’ll believe it when I see it.” “Good thing you don’t do your own cooking. I tried a sandwich you made that one time, and it did not taste like a sandwich.” Suggest things you could do together. “They finally opened up that new rollercoaster at the theme park, wanna come with me to try it out?” “We should go to that new laser tag place sometime!”
