This is to no rapper in particular and everyone in general.
Dear Mr. Rapper,
How's it going? Love the music you've been cranking out. But, really fast, I wanted to get at you over your new dedication/tweets/hoodie pics to the late Trayvon Martin. Not "get at you" as in beef. You didn't forget him yet, did you? I know you just put out some somber dedication to him just the other day.
