“Do not do to others what you can’t tolerate”, “Treat the way you want to be treated”
Everyone’s tolerance thresholds are different.
What might irritate me may not be an offence to someone else.
So how do we truly define or justify this statement?
Only extremes can be clearly judged.
The rest remains a vague space where we never fully know which of our actions might strike the wrong chord with someone.
