Hey mz Hartz- That reminds me of the time my ex and I were e-mailing back and forth. He was being especially ugly, so I responded that "other than your grammatical and spelling errors, you sound just like your father". He responded back, "your such a b!tch". It was so comical that he screwed up in just one sentence. I didn't have the heart to bring it to his attention and just let it go.
Oh man, that would be hard to keep my mouth shut on! "What's a 'such a b!tch'? Do I own a 'such a b!tch'? And if I do, what about my 'such a b!tch'?"
