Can anyone recommend some good behaviors for someone who just started behaving?

Commentary:
"Ah, a newbie in the world of behaving! 🤔 How about starting with the classic 'Don't chew with your mouth open' or the always popular 'Don't talk with your mouth full'? 💁‍♂️ Remember, behaving isn't just about following rules, it's about making the world a better (and less cringeworthy) place! 😄"
