Here are the players in this tragedy . . .
Me -

SG - Single Girl - Works a full time job, no children,
travels freely, extremely dedicated to family and friends but expects the same
in return.
PRG - Practical, Reliable Girl - has two boys, she worked until having children, husband is a VP of a small company, they are comfortable.
UTG - Up Town Girl - has one early elementary school age
child, husband is very successful, and she is very busy but does not have a job.
So . . . and we are sad . . Our friend isn't the same girl
we grew up with. That we went to school with, that was a bridesmaid in our
wedding. She is different from who we know her to be . . . we are at a loss.
