The best Christmas gift, for me, is the memory of Christmas when my kids were young and I would help Santa out. I visited the kids in their cribs dressed as Santa and gave them their first gifts of the day. I also appreciate more now why Santa stuck me with having to assemble some of their toys. It was frustrating at the time, but makes for great stories now, like the time the chimney on their play house roof ended up on the other side of the house from the fireplace.
The worst gift I ever received was a "shower kilt." It was basically a towel to wrap around your waist after showering. I could probably use it nowadays, but as a pre-teen...it sucked!
I have to agree that a towel is a worse gift than socks for a kid. Good for you to do the Santa dress-up. I think that would be so rewarding :)
I have a nearly two year-old granddaughter in the house...maybe this is the year to dust off the suit.
