When I was your age and still dating, I was never late to pick up my date. If too early, I cruised around the block until I could knock on her door at exactly the appointed time.
Yes, my dates were such that I did not want to miss a single minute with the latest miss. But to this day I am never late for a meeting, business or casual.
However, being on time for formal meetings has two serious drawbacks – wasting time waiting for latecomers and then listening to the meeting chair recap the meeting for the late latecomers.
Many a date who kept me waiting had real charms at play, but I have yet to find the charm in those who keep me waiting at work.
And as for chairpersons who think it polite to recap for latecomers, well, I politely suggest that you are being rude to us who bothered to be on time.
