Last Christmas my oldest was 5 years old and he started to discuss with me how Santa goes about entering the house.
"Dad we don't have a fireplace, so how does Santa get in? Does he come in the window?"
"Yep. that's what he does."
"uhh, dad?"
"Yes son."
"Does he call before he comes?"
"What?"
"Well I know you would shoot someone sneaking in our window, so how do you know it Santa?"

So the story goes, Santa calls before he comes.
