See, when I go out for walks, I like a shuffle. Got it just for that purpose.
It
really just depends on the person.
OP, pretend to be on the phone and that someone is asking you a question. Say, "Oh, Lord, I have no idea. I can't help y- Wait, hold on a sec." Then turn to the teen in question and say, "Mary wants to know which is better for a teen, nano or touch?"
The teen in question will then tell you which one they like better and you can go buy that.
Good luck!!
