memories
I've only ever had two, and both times the FB got attached to the SOB (me) and then things took a turn for the worse. Actually, I am still good friends with FB#1, but there is absolutely no F'ing going on anymore.
#2 stopped being an FB after asking to spend one Saturday with me shopping, having dinner and going for a movie. I recoiled in terror and must have blurted out, "You mean like BOYFRIEND and GIRLFRIEND?!?!?!" My reaction was not well received. There would be no more F'ing after that.
Both women were in their mid 20's at the time. Now they're both in that nesting phase of their lives, looking for Mr.Happily Ever After, and not Mr.FB.
Ahhhhh as someone said... the good old days. FB's are had to find - but once you find one, speak as little as possible, and enjoy the "ride" for as long as it lasts!
