What should I do when I meet someone who talks at dinner?

You shouldn't smack your lips when you eat. Some people clap your mouth, which is a bad habit. It is a habit to smack your lips when you eat something delicious. If you are his lover, you can tell her, change slowly, take your time, and you will be fine. This disease is not a big problem. But he is annoying. He eats well. If it's like this at dinner, tell her she'd like to eat outside. Don't affect others' appetite here. If you are an outsider, you can eat in a bowl and let him know that he does not oppress others and that others disturb him.
