At 59, I've never had a problem with it. There was a guy I was working for who used to mention my ''knobbly knees'' but I soon realised he was overweight, overdressed and drove a gold-coloured Lexus, so it never was never going to bother me. I took it as envy.
But if it happens to me, I'm now preparing my riposte. How about, ''I'd prefer it if you looked at me in the eyes rather than in my thighs''?
I remember when an ex boss got an IS200 as a company car around the time of Alan Partridge, it was hilarious as everyone tried to drop subtle hints into conversations.
