Keys

Yesterday morning I was trying hard to get my computer work done while Preston was doing a great job playing by himself.  I happened to look over when I heard him come into the office on his car and noticed something a little odd.  Apparently he knows that you need keys to drive a car so he went and got my keys from my purse to use in his car!  When I tried to take them out he cried, "NO, mama.  I have to have keys to drive my car."  I'm not sure what it is about keys, but if he sees a lock he instantly wants to try my keys in the hole . . . everywhere we go!
