I just had an interesting bedtime discussion with the four-year old ... Among other things, I learned why your nose grows.
It started out innocently and lovingly enough. I was giving him a "bunny kiss" (that is rubbing noses) when I told him that it was hard to give bunny kisses when he was a baby because his nose was so tiny. But that it was much easier now that he had grown. Cute discussion, cuddly moment - right? This is what he replied:
"When I was little, my nose was too small for my finger. Now it has grown and my finger fits all the way up in it. It's big now."
There you have it. Your nose grows to fit your finger. Not to give better bunny kisses.
