It's $*@)%&%)#@$( frustrating when the people on the other side of the project I've pretty much spend my entire professional career on can't get their !$^%$^!@$%!#$ acts together. They're the side that's currently getting paid huge &*#^@%$ amounts of money to do...nothing.
And it's not the fault of the person I was dealing with today - she's a sweety who's doing the best job she can with the (faulty, clearly) information she's been given, but damn if it doesn't get frustrating!
I could be doing something fun like crashing our firewall instead of playing with overgrown spreadsheets.
