Agreed, you gave a reply, for which I thanked you, but you didn't answer the question.

If it were possible for me to answer the question, I wouldn't be wasting the board's time, your time, nor my time, asking it.

When arrangements change, I want to know why, and if the change is down to me I would explain the reason eg my flight is re-routed via another airport which would make me 4 hours late for a meeting.

Feel free to find implications within that example.

Be well
