"Familiarity breeds contempt."
Perhaps we've got too used to each other's stances, and ways of arguing.
We need something to stop it getting stale, new people probably.
Perhaps we are tending towards scrutinising each other, in a pedantic way now, ( splitting hairs ) we have been members so long.
I've noticed people get the huff, hence the Rhiannon Flounce 😉💐
