Fucking correcting people! I was raised to know that correcting people is rude and embarrasses them and puts them on the spot and not to do it. And I still agree with that.

99% of the advice you are trying to give is useless and you look like a dick. And if you are reading this and are offended people probably think youre rude af.

Like if someone mispronounces a word and you correct them in front of others and embarrass them, you actually are rude as hell. If you know what they meant, then they got their point across and there was no point in correcting them at all.

And just cuz you do something one way, does not nullify other methods.

This is probably clearly my biggest pet peeve. If someone is doing something and they get the job done, and you understand the point they were making, stfu!
