No Jim- of course you don't owe me anything. If you want to do a bait and switch, fine by me- but you're the one that brought your income up in the first place!

Further details would make a great deal of difference- but as they might undermine your arguement I understand your reluctance to provide them.

Abusive? C'mon Jim- I didn't say you were bullshit- just your argument.
Since you wound so easily I'll try to be more careful.
