I give a few pieces per kid....but ONLY if they say "trick or treat"! Just holidng out the bag isn't good enough.

Once upon a time I would give myself a piece for every group of kids who came to the door -- a practice I no longer endorse

Towards the end of the evening I give more away as I don't want too many leftovers!

(The questions is...do you get candy you like so you can eat the leftovers or candy you DON'T like so you won't eat the leftovers!)
