Now, if I respond I'll seem petty since I'm sitting pretty right now with my dough.  Oh, well, I haven't anything better to do this morning since I no longer have to spend time collecting past due invoices. 

I really am starting to become concerned for Jim.  The stress must be getting to him.

But while her method did work for her today, it has severed any chance of future work...

Is there/Was there EVER the slightest chance that I would ACCEPT work from them again?  Since Jim continues to put forth the idea that I have burned bridges that might have been needed later, I recommend a mental health day.
