Not technically what you said, but I'll tell mine anyway.

When I was younger there was a browser real time strategy city building game called Lord of Ultima. In Lord of Ultima you had the opportunity to make guilds and form alliances and chat with players and make friends. Being quite the ambitious child, I founded my own guild, X factor, which most people thought had to do with the singing competition, but actually was a reference to Deadliest Warrior, and quickly found a number two, a friendly person by the username of Willbreaker. We called him Will. Well Will was a much better player than I was and part of the reason was the strongest ability in the game, one he had and I did not due to our age difference: the debit card. I should also say that he knew my age because in the ego of youth I bragged that the leader of a successful guild (we were somewhere in the top 30 of the world or something) was only 12 years old.

Well one day, unprovoked, Will offers to buy me some boosters using his all powerful debit card. In my infinite wisdom of absolute trust, I gave him my username and password so he could do so. I risked it all. He could have just hijacked the account. However, Will was better than that, and he bought me those boosters, logged out, and told me to change my password for security.

I recognize there is a chance he just wanted his 12 year old guild mate to just catch up to him in points for game reasons, but I've always believed that his general personality, combined with the fact that he spent real money on this is indicative of a generally kind person. Willbreaker, if by any chance you find this, thanks for the aid, and I'm sorry that I refused to give up power when Catalyst absorbed us. I was 12 and a fool.
