2. Refereeing
If your teenager is a sports fan with particularly thick skin, why not have them consider doing some refereeing or umpiring? It’s a relatively easy way to make money as a teen!
They might need to do a short course (although that’s not necessarily a requirement in all settings), but it’s worth it.
Of course, the “thick skin” comment was merely in jest – a teenager should be able to take the inevitable complaints of younger children without too much fuss!
