One of these things is not like the other one

Here is dear, sweet Jack at the Birthday Party for Jesus this past Sunday. You will notice all the other children are dressed as angels; except Jack.
"Jack, are you going to be an angel this year?" me
"NO, angels are girls." him
Technically not, but fair enough the kid doesn't want to wear a dress!
Oh, and the other difference is that Jack was actually singing.
Tonight we're heading off to his Christmas program at preschool. He's so excited - he gets to wave a scarf AND throw it in the air!
