Daddy's drawing game

I love watching my husband get creative when he plays with the kids.  I recently spied on them as they were drawing on the train table.  My husband would draw a couple lines or a circle, and Mini Me (Little Lady did some, too) would add to the drawing and explain what it was.  

A few parallel lines became a gate, then a fence, then a flyswatter, then a smiling mouth.  Half a heart turned into sunglasses, a face, and a purse.  
This is a pretty common elementary art activity but I was proud to see my husband think of it and really get into it.  
Plus, everything is better on the train table.
