Oh Well, Summer

Three years ago, I received from Scott Alexander the letter of admission to Connecticut College, along with the financial award of $42,490 a year.

Tonight, it's him again to send me another letter, which again, is highlighted with the keyword "Congratulations" and is followed by a fellowship of $10,000. Is there a word for "the one who brings good news" so that I can address him?

Although the feeling is not as hyped as that one, although I think luck plays an 30% role this time, and although I have vaguely anticipated the result, I still can't help smiling and cheering to self.

Why not?
