Why this works
It commits. You’re in — in some form — and everyone can plan around that. “Maybe” is what quietly deletes friendships; a branch never says maybe.
Every branch is pre-authorised. When the smaller version happens, it arrives as the plan working — not as you failing. Nobody has to forgive anything, because nothing went wrong.
It was never the cancelling that cost you people. It was unpredictability with no protocol around it. People can plan around weather; what they can’t plan around is a mystery that apologises.
