Nice story Shabbir, had read this long ago. good to read it once again.
It's not hard to find such people but the problem lies in us.
We overlook such people, we don't understand them even if he's the person next to us.
These kind of people don't wait for someone, they come, make your day even by the smallest deed, and move on. It's on us how we interpret that deed and feel about that person.
