The Boy is still in a Christmas state of mind - it made an impression this year. He has also developed a keen interest in dinosaurs of late (what is it with toddlers and dinosaurs, anyway). To that end he offered this statement to his mother last night:
"Monsters and dinosaurs don't get any presents because they just eat them... and people too... and people don't like that... because it hurts."
And that is why dinos don't celebrate Christmas, and why they are rarely invited to parties, I assume.
