Sleep Walking

Cole occasionally sleep walks.  Most of the time he will just wander into our room and stand there for a few minutes until we tell him to go back to bed.  The other night I heard him get up and go in the kitchen.  I figured he was going to get a drink.  Then, I heard the garage door open.  I got up to see what was going on and by the time I got out to the garage he was in my car, in the drivers seat.  I asked him what he was doing and he said "I'm going somewhere."  I told him he needed to come and and he said "no!"  I had to go out and get him and carry him in the house.  He was so mad that I made him come in.  He sat in the corner of the room and cried until I put him back in bed.  Needless to say we will be getting childlocks so I can sleep.
