WR, That is definitely odd behavior, but I've heard of this before. They come and park in the driveway or on the street and just sit there w/the engine running. It's almost like they get there and then don't know how to come up to the door and ring the bell or knock. Then again, it could also be a "visual visit" to see that the home is still there and looks the same.
There's really no way to figure out the why of this visit...but he's got something on his mind and doesn't know how to communicate it just yet.
Continue to be patient...the answers will come.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
