And Santa's reply (I cut out full name & our town, but you still get the idea):
I can't even tell you how excited GM was to open a letter from Santa today. He's been back and forth on whether Santa will come visit. Now, I've never threatened that Santa won't come, even when he's being awful, but somehow he got the idea in his head. Last night, he started crying at bedtime that Santa wasn't going to come because he hadn't been "all that good today." The letter arrived at a perfect time and calmed his fears on Santa skipping our house this year.
