MSN

Every Morning when I get to work, I turn on my computer and sign in to msn. And every morning (days that I'm at work) I say Hello To Mr Ben P in the UK, AND every morning I get NO reply.
Now for a while I thought because of the time different he would be away from his computer so I started to change the times of my Hello to a afternoon hello. Now I don't sign in and sign out right away. I usually stay sign in from 8am till 5pm. Expect when I go to lunch from 12 till 1pm.
So the question I'm asking what have I've done wrong to upset Mr Ben P.........
