Freaking evil of the gub'ment take 2

So the IRS finally got around to replying to my revised return (which I sent in months ago). They have decided that they don't want to send me that much, and would like me to sign off on a re-revised return saying that they owe me $200 less. Once again, I have 3 weeks to reply to this. Once again, I'm sure it will take them 3 months on their end. And they'll probably re-re-re-revise the damn thing. So it seems that if I'm lucky, I might get the money they owe me by the time I retire.
