As I got a downvote I can only assume my tone came across as “how could you not know this?”, but my feeling when I wrote this was that it’s a bit of a funny and interesting anecdote the parent wrote and I’ve been similarly frustrated with how I easily make mistakes with seemingly simple tasks such as putting up a shelf, to which I have to laugh at myself about when thinking about it many years later.

I definitely prefer that with software it can be “perfect” and easily changed later if you find it’s not.
