They decided to be there.
They decided you were a good decision – at least, the best decision for that moment in time.
For most, it was a series of decisions that brought them there. Decisions based on relationships. Decisions based on trust. Decisions based on history and knowledge and circumstances.
If you don’t show up, they will make another decision.
And the magic to bring you and them together is passed. Maybe, it will happen again. Maybe not.
In any case, it won’t be the same.
You decided not to be there.
Good things happen when you show up.
