Someone told me this story recently:
'I hadn't met her before; we made eye contact, and agreed to dance. As we embraced, I noticed that her cheeks were naturally well-coloured, but in particular the right. We danced: at first we made contact cheek-to-cheek, and then she shifted her head awkwardly, and couldn't quite find a place she found comfortable.
'I'm sorry about that' she said between tangos, 'but I've just danced with two guys who hadn't shaved, and I dance close, and it's really made my skin sore.' She pointed to her right cheek: not only was it redder than the left, but also it was slightly swollen. She touched my cheek. 'You're fairly smooth' she said. 'Normally that wouldn't bother me, but my cheek is really sore.' I was astonished: to my knowledge I've never danced with anyone whose skin is that sensitive. Anyway, she settled on a position with her ear close to mine, and we enjoyed the rest of the tanda. Perhaps the position wasn't ideal, but it gave us a stable head contact.'
There you go, guys. Not everyone will appreciate that designer stubble when you go dancing.
