There will be times when you make a decision that 20:20 hindsight reveals to be flawed.

There are also a precious few that come unbidden, without agenda, and make life a delight.

My Grandmother said, “if you want to have a good relationship that lasts, remember when you disagree, if you are wrong, apologise quickly, but if you are right, say nothing”.
