These idiots call up and left no message. WTF??? Caller ID says 'Anonymous'??? And I don't even have any student loan??? [***] go back to school you might learn something!!! Ooops, sorry!

Who knows??? As the saying goes ---- "hope springs eternal". Though in this case, might be more on the eternal side.
