OK, maybe on the surface it doesn't sound like the most exciting activity for Halloween, but there are a lot of benefits to staying home and serving trick-or-treaters. First and foremost, you're clearly allowed first dibs on the leftovers. Second of all, you get to see some adorable kiddos dressed in their favourite costumes. And lastly, the designated candy giver can also come up with fun ways to spook people that dare to come to the door.
