I like to think of myself as a supportive friend who likes to help others. It feels good to be able to help others and show that someone cares even if they dont know you.
As that quote from "V For Vendetta" goes:
"But what I hope most of all is that you understand what I mean when I tell you that even though I do not know you, and even though I may not meet you, laugh with you, cry with you, or kiss you: I love you."
It is a beautiful and touching scene and I suggest you watch the movie or at least that scene (just look up "v for vendetta valerie's letter" it should show up...)
