When I moved Christmas tubs around to reveal our outdoor nativity set he looked at it and said, "OH! I forgot about that!" (Christmas decorations are so fun with kids, I love how they seem so new and exciting, but yet elicit memories for them at the same time.)
Then he said after a pause, "We are really big fans of Jesus aren't we?"
That is pretty high up my list of my favorite things my kids have ever said.
