Years ago, my husbands old boss flew his plane around looking for our house. He said he saw the cars and remembered the new building we told him we where woking on, thats how he knew it was our place. The next day he was knocking on the door! At first it did freak me out some but, after awhile we got over it and just laughed at the thought of him flying around looking for our home.

The fact that he told you he did that, should ease your mind some. If he was up to something wrong, he would have never told you.

It is a little odd, but I would just ask him why. Be honest and tell him it kind of struck you odd that he looked for your home and you are just wondering why. Just don't make a big deal out of it to him. Make a joke out of it, tell him "What are you planing on checking me out next time I call in sick?" laugh and see where it goes from there. One: maybe he relize that he over steped his place some and Two: maybe it will ease your mind some what, if you get a answer.
