When you have your next gathering, please be kind and have the squealing girls and the guys dropping the f*bombs in the loudest voices possible go inside at midnight. In the quiet of the dead of night your voices really do carry very, very far. The rest of us in the neighborhood really don't care to hear your conversations...or squeals...or swearing. Really.
A tired, irritated neighbor trying to be nice, who next time will get out of bed and figure out where you are and call you and not be so nice.
