How to avoid getting in trouble for having a party?

This weekend my parents are out of town so I decided to have 5 people over. Small, casual everythings fine. About an hour later, I walk upstairs and around 30 people were here. They stole my parents alcohol, my iphone and broke the door off the hinges. I know its my fault for having a party but I wasn't expecting this much and I need to know what to do, how to fix the door and if I should just be honest and tell them the truth.

Being honest is the best thing sooner or later they will find out anyways

Clearly you invited the wrong people over, who are not to be trusted with these things.
(whoever invited the other 25 people should be berated)

In any case, damage control, clean up as best as you can and tell your parents honestly what happened.

Try to figure out who stole your iPhone and make attempts at getting it back.

The door is probably too hard to fix on your own, your parents may be able to help with this.

Bottomline, tell your parents what happened, though they will be angry at you (as they have every right to be) they will also know what to do to solve most of the problems remaining.

You *** is grass, kid. You are done.
