HELP!!! UNDERAGE DRINKING!! PLZ HELP 10 POINTS FOR BEST HELP!!?

I'm sure your parents expect to have to "police" the party already, but it would still be a good idea for you to let them know that you've heard some girls are planning to sneak alcohol in. Have a sign posted, or have an adult make it clear to your guests that anyone caught drinking, who is not of age to do so, will be asked to leave the party.
