I'm guessing the person in question got a job.

And if you want any freedom at all from your parents ... that should be a priority. Get a job and save up some money.

I hope that in these pleas to go on a tour you are not asking your parents to fund: a) the tour; and b) your schooling next fall. If I had a kid who wanted me to pay for everything while he/she went off and had fun, I'd be saying "no" too.

I just finished a 4-year degree. My parents were nice enough to give me a roof over my head for most of that time, but I worked my butt off to pay for everything else ... part-time jobs during the school year, and usually 2 jobs adding up to about 60 hours a week during the summers.

Getting a job and paying for some/all of your own expenses would be another way to show you're a mature adult.
