I think that what happened to the F3 boys was that after coming home from the Falklands, they were so shocked by the loss of their lovely, compliant, wooly girlfriends that they hit the beer.
Of course, off to the mess, 3 pints later and the beer goggles kick in and ..........hey presto, you are now engaged to be married and she has 27 witnesses to the proposal!
Wonder how long the list of volunteers for the Falklands is these days?
Good mate of mine is on F3s and his girlfriend is lovely - but note "girlfriend" not "wife"!
