One Way Ticket to the One Way Sign

Louie loves a one way sign.  This is in no way sarcasm or joking.  When I open the front door he wants to book it out the door and down the sidewalk.  Now, when I say "book it", I mean the fast crawl.  On concrete.  Doesn't that hurt?  Seems like it would be an incredible incentive to walk but...I digress.  

I have always just assumed that he remembered the way to the school's playground located behind our house and that's where he wanted to go.  What kid doesn't want to go to the playground any chance he gets? One day I took his hand and followed his lead.  Down the sidewalk to street where you would turn left to continue on to the school, he stops, crawls over to the sign, pulls up on the sign and pretty much looks like the happiest kid I've ever seen.  Glowing happy.  Pure joy happy.  He looks at one side, then the other, amazed that it says the same thing on both sides. So be it.  We make trips down to the sign every few days now.  Sometimes just he and I, sometimes with the therapist, sometimes the whole family.  This gives a whole new meaning to "I wonder what the neighbors will think."  

Isn't it all about expectations?  I would expect Louie would want to go to the playground.  I would not expect Louie to fall in love with a one way sign.  Or that he would love microwaves or mailboxes.  Most kids love playgrounds.  Mine just happens to love street signs.
