In person (preferred), or phone convo if that is simply not possible. NO EMAIL.
E-mail as immediate follow-up, to reiterate, state points you missed, clarify, etc.
Will explain later. Off to watch football with my boys!!
Not sure in person is a viable option... Although she is planning on coming down to S. FL at some point next month to pack up the rest of her stuff to bring back to C. FL... Although I don't know if she'll be coming alone or bringing friends to help... So I think phone is the best option.
I'm CERTAINLY planning on an e-mail follow up just after our conversation, probably restating exactly what I said (or more likely exactly what I WANTED to say!)... Kinda a best-of-both worlds approach to ensure she hears the conviction in my voice and then has it in writing.
