Cake may be the happiest food we know (although you can eat and enjoy it no matter emotion you're feeling). Only a friend offers you cake. Imagine hating someone and asking if they'd like some cake. That goes against all rules of humanity.
So, go out and enjoy some cake, especially if it's your birthday.
