When I politely turned him away he asked to see my mother, presuming I wasn't the grown-up of the house.
Then there was the time I was leaving trendy Shoreditch House in the East End with my 25-year-old daughter Catherine, and, while she went off to get a cab, a group of 20-something men invited me to a party.
As a result, my body was low in minerals including magnesium and B vitamins, as I was unable to absorb nutrients however healthily I ate.
This also accounted for my loss of memory, dry hair and ridged nails.
My teeth are one part of me that I'm tempted to 'upgrade' by bleaching them back to their original baby white.
Within days of taking them I began to feel more like my old self. I eat good-quality protein such as organic chicken or fish, and organic vegetables every day. I use a cheap supermarket moisturiser and stopped putting my face in the sun when I hit 40. But there are other cosmetic ways to cheat the ageing process.
No Botox, no fillers, nothing scraped back, tucked in or plumped out. Most women, on finding out my true age, seem eager to know how I do it.
In New York, where I spend a lot of time - I'm a Londoner, but my 57-year-old husband Charlie works as an American TV producer - people automatically assume I've had work done and ask for the name of my plastic surgeon.
Yoga and Pilates are great for women of my age, but I love walking.
When I was at the height of menopause mayhem, my husband bought me an adorable chocolate labrador called Bailey - no doubt in a bid to get me out of the house.
I've been having highlights for decades, but when I turned 40 I switched from bleach-blonde hair dye, which can look harsh, to more forgiving caramel tones, which look warmer.
