Returns... Atleast Favours

There is a friend of mine, who really was in some urgent need of funds quite some years back. I tried to help him with whatever was possible from my end. I even went out of my way to do something more. Ofcourse, I know for sure that, my help was really the biggest for him at that point of time.
Then ofcourse, years have passed by & I haven't got any info from him. So, I started pinging him may be sometime during last August. The response is so delayed like I got to wait atleast for a month. The response is also vague enough but positive. He doesn't even want to share any more of his contact details like mobile or so. Even during my heights of emergency too, I couldn't get his hands return back my favour!! Time, people, mind...
