I think it’s a healthy thing to do to admit when your wrong as it places importance on truth rather than self image.
Some examples:
I thought pay-per-view was paper-view because you had to fill out a form to watch it.
This morning I insisted there was a noise outside to my partner and it was in fact the refrigerant in the fridge gurgling.
I thought the cat wanted to be pet— it did not.
My grandfather used to say this all the time. He was such a humble man, too, so it always got a good “dad joke” chuckle. Glad to see it’s still out there.
I picked it up from an episode of Deep Space Nine. Good times.
