I will never understand how there are pretentious people! If someone asks something, it is because they want to know, and if you know it or have experience, don't be arrogant; don't respond with mockery or sarcasm that makes the person feel less or bad. If you know it, explain it to them, and if you don’t want to explain, tell them or give a reference to some page or video. No one is born knowing! And not everyone has the same mindset! If you won't help, don’t comment on things that make the other person feel bad. $BANANAS31
