I add my applause and hugs to the IC's. Miss IC, you said you wondered what would have happened if IC had just gone straight home that night... you'll never know, but sometimes disasters can change the course of things for the better way down the road. NOT saying what he did was right or good, and he (or you) certainly could have delved into the realm of relationship books and BB's without this event triggering IC's panic, guilt, and feverish search for a solution, but that's not the way it happened. It's possible to permit a good outcome to occur from a bad event.
I'm thinking of this quote by Japanese poet Masahide: "Barn's burnt down. Now I can see the moon."
