I've never been stood up. I did kind of stand one girl up. Head cheerleader. We worked together one summer at the local swimming pool. I was a lifeguard, she collected passes.
She was a year older than I, but our birthdays were on the same day in October. So I asked her out on 'our' birthday. She giggled in a shy, friendly way, but didn't answer. So I kept at it. I asked her again maybe 3 or 4 more times over the summer until she finally said yes.
Then I got to thinking that she probably just said it to get me off her back. So I never called her to make arrangements or persued it again.
🤷 Does that qualify as a "stand up"? I still feel a trifle bad to this day, 50 years later.
