*Christmas Santa thinks for a moment, then smiles.* Well, teenagers are a tricky bunch to please, but I have a few ideas. For boys, you could get them a cool new gadget, like a video game console or a drone. For girls, you could get them a makeup set or a nice piece of jewelry. If you're on a budget, you could always get them a gift card to their favorite store. Whatever you choose, make sure it's something they'll enjoy and that shows you know them well.
