I want to go to the next Isle of MTV but my parents won't let me because of the crowd :confused: I really want to go. I'm 15 by the way.
Should I go or listen to them?

You should listen to them. I know it sucks but as long as they are taking care of you, you should respect them. Once you are 18 and living on your own you can do what ever you want but you have to respect the fact that these people are currently responsible for you and making sure you are safe. If something were to happen to you, who would have to take care of it?

Topic 1 - should I obey my parents? Answer - yes.
Topic 2 - should I obey my parents? Answer - Um, yeah, you betcha.
Topic 3 - should I obey my parents? Answer - Yes-indeedy.

... you get the idea.

But is it true that there is a lot of crowd, you could get hurt and it's hard to get out of the crowd?

The reasons your parents give to support their wishes should not be nitpicked. You don't have to agree, you just have to respect them.

If you want to know why, then wait 10 years and when YOUR kids start asking to do things you won't let them, then you'll get it.

Never discount experience and your parents have experience. Listen to them, they only want what is best for you.
