I wanted to use this as an opportunity to infuse yet more classless-hick-sarcasm. I wanted to ask why people make such a big deal about birthdays, especially to internet non-people. I guess I don't dislike you enough to be a complete dick or maybe I like you just enough, who knows. I don't know the other Rain brother, maybe I would like him more, maybe less, but in either case including him seems pointless.
Maybe by your next birthday I will be better at the traditional salutations, maybe I won't.
Today's your birthday, good for you.
