He actually did delete his profile, and because of a conversation with me no less. And the only thing I told himw as that he should try to focus on the things he had, rather than what he didn't have, to take a more positive attitude in life. Then he said: thats it, I'm deleting my account. And after all our nice converstations as well.
I feel sorry for him and didn't mean to offend him at all, but the easiest thing in the world is to make this guy unhappy.
