When I was a kid, we had no fireplace, so Santa came in the front door. I had to make sure it was unlocked for him before I went to bed. We never thought to give him a spare key.
He left my presents unwrapped.. sitting all over the living room I remember one year my fave stuffed animal monkey got missing or eaten up by a dog and Santa brought me another on Christmas day.. it was sitting in the living room chair HAHA!
I always wanted to leave milk and cookies out for Santa, but my Mom (wink wink) said nooo, Santa is sick of milk and cookies at every house.. let's leave him a piece of chocolate cake and a pepsi here, he'll like that much better
