When one member of a couple achieves something, it is customary for the other member to be happy for them. They might congratulate them. They might, in the advent of social media, do it in a public setting. No more skywriting for you. Now you have Twitter!
Notable person Kanye West chose to congratulate his wife in such a manner. Why? Allow him to explain.
For her part, Kim thanked him in an equally Kimye-esque way.
Ah, love. Who needs Facebook-official when you have Tweetstorm-official?
