Not about money in my case, but similar stuff happens too. I just stand my ground and say as calmly as I can (with varying levels of success) “I’m sure X happened this way” we don’t discuss it often, my dad usually just keeps up believing stuff happened his way, and we leave it at that.

What helps me with those kinds of things is to focus on enjoying the thing, whatever it is. Especially digital stuff that occupies no space in my home, I accept that it’s ok to do something as long as I enjoy it, and when it becomes repetitive or boring I can just stop.

Of course sometimes you need to push against this a bit when you know there is a slightly unpleasant section blocking more enjoyable content. The big takeaway is that it’s ok to stop if you’re not enjoying yourself anymore. No one is gonna check or care.
