We have a set of wooden, interconnected “roads”, similar to the Brio train tracks.  Matthew loves them, but sometimes struggles to put them together.  Benjamin loves his snacks (he is my son).  Today, Matthew didn’t finish his snack and Ben asked if he could finish them.  Matthew told him he could if Ben helped him put the roads together.  So, Ben put a few together and then asked if he could have the snack.  Matthew said, “Not yet!” in a sing-song voice.  This want on for about five minutes, until the road was stretched out across the living room and Matthew played happily as Ben ate the snack.

Very interesting that Matthew has figured out how to barter already.  I couldn’t stop laughing.
