People who know me often ask for a strictly yes or no answer, and I don’t comply.
It is based on a fear of getting things wrong, or that people will misunderstand you. So the idea is to be as unambiguous as possible. Which means a deep dive.
For example:
Do you want to watch the All Blacks match at the Nags Head on Saturday? Yes or no please Rob.
But I won’t stay if I have to stand, and I won’t stay if it is too loud, and I won’t come if there is a family emergency that takes priority… but yes, sounds good.
