She has argued with friends about it. Some see beards as a cover-up - what's the guy hiding? But to her they mean respectability.
People are very polarised about men with beards. In general, they either love them or hate them. The pro camp like their masculinity and find the man more attractive than his hairless mates. The anti faction find them pointless and distinctly off-putting. Women may find kissing less enjoyable if they're negotiating a thicket of hair.
Personally, as you know, I'm not keen on beards. I had one briefly in the seventies when I fancied the John Lennon look, but I've been clean-shaven ever since. Those men who grow their beards to absurd lengths just look ridiculous.
Also, beards need constant upkeep. They have to be trimmed, they have to be kept clean, bits of food get stuck in them. Who knows what you might be kissing? And they can be horribly itchy.
But beards are very fashionable nowadays. I see more and more men with them. Maybe they simply can't be bothered to shave. Maybe their partners prefer them with beards. Maybe they're just proving they're man enough to grow one. Or maybe their religion requires men to have beards.
Fashions come and go, though. Apparently in the mid 18th-century being clean-shaven was seen as the height of manly sophistication, and very few men had beards. But facial hair was so important to the Victorians that many men, unable to grow their own, were forced to buy false beards and moustaches.
So would I trust a salesman with a beard more than one without? No, it makes no difference to me. What I'm looking for is a trustworthy product.
