You are that person who is kind, to convince yourself of this you do a nice deed for a total stranger every now and then. You are going to make a donation to some website "because you can" it doesn't really matter who or what it is. As long as you get the feeling this "you being cool" may be true after all. So go send a donation to that homepage you like so much. It's so freaking hard to make a buck online it's probably worth 100 times as much the moment you let go of the coin.
And you are going to feed the birds so that they do not get the flu.
Now think of yourself as a better person but don't allow anyone to find out the how and why. Or they will think of you as a lunatic.
