What to do ?

Well, again i have been presented with a most unusual situation.

The past couple of weeks I have posted that God has a plan for me and I'm still not sure what that is.
The situation I'm might be the way he is leading me. I hope not, but that not for me to decide.
For the past few weeks I have been working directly across from someone............. let's just say he is one of a kind.

We have all heard " Well, he's just a dirty old man."
Well, this guy admits to being just that, in fact, he calls himself that and takes pride in that fact.
He is 50 something years old and he's married to someone who is her 20's. Please understand that age is not THAT big a deal to me, but that causes me to wonder.
It's not it, not by a long shot.
He proceeds to tell me the things that he and his wife like to do in private.
I DON'T KNOW THE GUY THAT WELL!
And he then giggles like a little school girl about it.

I believe that some things are meant to be kept private. Relationships at home is one of them.

Now, for my dilemma. WHAT DO I DO!!!!!!! I mean he is pushing himself beyond the bounds of harassment and I am trying to ignore him thinking maybe he will go away or take the hint.

For the first time in a long time, I am at a loss of words when I talk to this guy.

If this is what God has in store for me, can I get a second opinion?
I honestly don't know how to handle the situation because I have never been in one like it before.

Any takers?
