A while ago I was walking down the street (in the UK) and a monk was walking towards me, he came straight over to me and said hi and shook my hand and holding my hand with both of his hands. I felt a bit weird at the time as I am not used to strangers coming up to me in the street to shake hands. But I shook his hand and said hi to be polite and went on my way. Only now I have just come across a post stating monks are not allowed to touch women including shaking hands. I'm not sure what type of monk he was or whether it is only certain types of monks that cannot touch women. And if all monks are not allowed to touch women, it is really weird he would come over to me just to shake my hand.
