What Does This Mean?

So, I have a 4 year old little boy who LOVES to sort things.  Anything.  Birthday candles, colored popsicle sticks, balls, crayons, cookie cutters, cereal, towels, candy, construction paper, stuffed animals, dishes...anything.  He likes to sort by colors, by sizes, by texture, by age, by number...any way.
 I wonder what that means?

He often BEGS to sort.  Sometimes he even cries because he wants...almost needs to sort.  "Mom! What can I sort?"  "Mom! I really want to sort something, can you help me find something to sort?"
 I really wonder what that means.

I had a T.T.T. meeting last night and when I got home, Lane asked me if we could sort something.  I told him it was too late to start that but promised we'd sort today.  So, this morning he sorted his legos.  Perfect for him!  Colorful, big, little...
Just what he needed. 

Today's mission...accomplished!
