I do, although I didn't remember doing so until recently; I was walking down a street near my place when a guy dressed as Santa was walking around (I'm not sure why) and a little kid FREAKED THE FUCK OUT, which I used to do too.
Christmas used to be a huge deal to me; since the age of 9 or 10 I was the one pushing my parents to buy more, More and MORE Christmas lights (early sign of eventual gay-dom?) and I would spend so much time outside hanging them on the house that my hands would go numb from the cold.
One particular memory I have of Christmas, was way, Way, WAY back in 1987. I was 8 and at the point when I knew Santa Claus was bullshit, but I still emotionally invested in the belief that Santa would drop off a truck load of Lego's. Or at least a sweet-ass R/C car. Of course I usually received ugly sweaters, but I digress...
This one night in particular I remember lying in my bunk bed and "hearing" the sound of reindeer on the roof, and getting all excited - to the point that I exhausted myself and fell asleep. In reality, it was my parents, drunk, and running up and down the stairs to put presents under the tree.
God - I am so painfully a Catholic boy.
