When I was about 17 (1964) I had the chance to go to a party with a friend of mine, who, at that time knew a lot of well known people. Now I know for a fact that the Beatles, Rolling Stones and David Bowie were going to be there (true!), but at the time I had a boyfriend. Now what happened was that I said I'd go, but just as my friend pulled up in his car to collect me, my boyfriend turned up as well. Out of loyalty (idiot) I said, sorry, best not to go as my boyfriend looked so hurt. BIG regrets. . I'll never know who I might have met and it might have changed my whole life!!
