Some responses to the PM's failure to get that a waitress was not enjoying his slightly juvenile but (he thought) harmless shenanigans, have been strident and uncompromising.
Unwanted touching is assault, they say.
I touch people I barely know reasonably frequently. Something about the territory. People come into my 'studio' and we get talking about art, portraits, lost loved ones, etc. The conversation can easily turn to personal sadness and it is my wont to touch someone's arm. Occasionally I might even hug someone. Never did I ask their permission.
Someone once asked me if it was OK to give me a hug (in the same environment). It felt weird.
We seem to have a subset of a generation that considers their right to not be touched paramount to anybody else's spontaneous demonstrations.
It's unnatural and anti-social.
