I began my matchmaking career with my father and stepmother, when I was only 12 (they are about to celebrate their 25th wedding anniversary). I must admit I'm a tiny bit obsessed with getting people together. No one was at all surprised when I set up a dating agency [].

Why do I do it? I think it's because I've been with my husband for 18 years now, so only have my friend's dating lives to enjoy.

My husband accuses me of meddling, but one of the most rewarding moments of my life was when I visited St George's Hospital recently – a nice-looking man came up to me, introduced me to his wife and told me: "We met on your site." In her arms she held a newborn baby – a beautiful baby. Now that's not meddling, that's matchmaking!"
