AAAAA, I'm definitely tired of walking on egg shells, tiptoeing around this coworker. I may use your line ("Generally speaking when someone does you a favor you say thank you, not complain.") on her sometime very soon. ; )

After her talk about how she doesn't "get the chance" to complete tasks, she blew off a meeting that she scheduled for her part of the project. I had to step in and handle it, again. Her response? "Oh [expletive]!" My response? "Oh [expletive] is right!" She absolutely knows she's screwing up; there's no avoiding the last offense. And -- surprise -- I'm not accepting the excuses or blame anymore! God, it feels good to say that!

Thanks for your help! <big hug>
