My table manners differ between environments. I know how to use good table manners when I am expected to, such as eating with the family or eating at a public restaurant.
I chew with my mouth closed by default. Sometimes I talk with my mouth full if someone asks me a question - when I do, I cover my mouth with a hand. If I have noodles, soup, or spaghetti, it's difficult for me not to slurp... However, I try my best to avoid it while out in public. I don't go out of my way to reach for farther away items across the table in restaurants, I ask if someone can pass it. Lastly, I do not begin eating until everyone else has received their meal when eating with the family.
I am not too fussy about table manners at home. I mean, it's your house and you can do whatever you want in there.
