Be aware that your claws may be sharp, and Human skin is soft, especially when not covered in clothing. It is polite to be careful and keep your claws retracted unless the Human is harassing you. Letting you loll all over their lap, or sleep in their bed, does not constitute harassment. Humans are not scratching posts.
Stealing is not only rude, but wrong. Conspiring with your sibling to distract the Human while chopping chicken so that you can jump up on the bench when the Human's back is turned, then pigging out on the chicken, will result in you both getting scolded and not getting your normal dinner.
Chicken farts are impolite and nausea inducing for humans - after stealing raw chicken, take yourself outside if you need to drop a clanger. Trust me, nobody wants to smell that.
Wrapping yourself around the Human's legs while they walk, lying in the shadows where the Human walks, and jumping out of small, high unexpected places when the Human walks by are rude and indeed dangerous. Flat Cat may result if the attack is successful, and that does you and Human both no favours.
