This story has been making the rounds on the various social networks the last couple days, but just in case you missed it, I wanted to post a link here because it really is quite the heartwarming tale. (Assuming it's true, of course with the interwebs, you never really can tell. But I like this one, so I choose to believe it really happened.)
The gist of it is that two brothers are in a game store, and the older one wants to buy the younger one a game. The younger boy wants a game with a female character, and a purple controller to play it on (because purple is his favorite). The father enters and takes umbrage with his younger son's selections, but that's when things take a nice little turn.
You can read the entire blog post here, and be prepared to have your heart warmed. It's just a shame that this sort of thing stands out. It'll be nice when one day this sort of thing is the norm!
