I knew someone once who had this, she didn’t know until she got an x-ray as an adult. The doctor called in their colleagues to take a look at the scan because he’d never seen a real-life case before. She had her heart on the right side of her chest, was pretty interesting.
Not me but a good friend of mine met a girl and lied about his job. He was already working a decent job as a floor salesman while applying to be a flight attendant which paid more money. He told her he already had the position he was applying for, which he never got and it kept snowballing until he could no longer come clean without major consequences. For 6 months, he had to make up a fake flight schedule, fake work-related anecdotes, etc., Needless to say when he eventually came clean she ended things, and I suppose he learned a very strange but valuable lesson. It was pretty funny to me at least.
