Boo! We hope you will help us celebrate this haunting time of year by joining us for a Halloween party. All the boys and ghouls will be partying at <location> on <date and time>. Costumes are preferred, but optional. If you’re normally pretty scary looking, by all means, don’t wear a costume! We ask that you please not bring your werewolves unless absolutely sure they’re housebroken. You should have seen the mess after last year’s party! Delectable treats, drinks, and garlic will be in abundance, but please bring your own wooden stakes and silver bullets if required.
We hope to see you there. Come prepared to be scared!
