i hate the extreme informality that seems to be de rigeur, or was, nowadays.
people in business or healthcare settings presuming to call me by my first name. even worse imposed hugging by nurses. it would seem churlish to object.
so now, we all have good reason to decline hugging/ kissing, politely but firmly. i do think that often we were brought up with the idea that deferring to everyone else's ideas was polite, and being polite was paramount, and others' feelings were always more important than one's own.
well no. it's taken a long time to change this mind-set. and longer to act a different way. but this current situation gives an opportunity, to just stand back from any attempted hug, and say, no, not me.
