A list I compiled a while ago. 🙂
Talk to them about what they want to talk about. Pay attention to them.
Invite them to church or a fun youth activity.
Tell them that they’re awesome and you love them. (It’s awkward at first but it’s worth it.)
Hang out with them when no one else will. Stick up for them.
Tell them what you believe lovingly, and then back it up with actions.
