LOOB

AAM - As a matter of fact (CLEARLY it's not)
BYKT - But you knew that
CID - Consider it done
CMI - Call me
F2T - Free to talk
HAND - Have a nice day
IAE - In any event
IYSS - If you say so
NRN - No reply necessary
PUKS - Pick up kids from school (I really think that this should be spelt out - the consequences of misunderstanding the acronym are not good).

I much prefer all the guesses in the last entry though, especially the idea of updated Abbey Girls.
