How can I convince my parents to let me see Taylor Swift concert?

Well that's a good idea, try that! And since the tickets are cheap I'm guessing you'll begat away and if I was you I wouldn't go cause I once went to a concert and I was on the floor but in the middle and I could barley see the artist so the only good seats are the ones at the front. Maybe you should just earn the money so you can go next year but you'll be in a really good seat
