When I was younger all my siblings and cousins would end our trick-or-treating at grandma's house. There we would sort out our candy, lining them in rows, and then do trades. There would be a total of 10-15 of us doing this, so the trading would last quite awhile. Grandma also provided cider and doughnuts, as if we didn't get enough sugar.
I know it is nothing crazy and scary, but it was family and we loved it!
