In Sweden when we eat we try to be as silent as possible. Being quite and not making slurping sounds is a sign of politness so it is seen as slightly if not very disgusting if you slurp or burp. The food is also slightly adapted to this custom since there are no distaster messes to deal with if you suck your spagetti silently. In Japan however, (since I’m there I’m making comparisons between the Japanese and the Swedish ways a lot) if you want to eat the right way for certain foods you should make sounds, and believe me if you don’t slurp (and suck in air) when you eat then there will guaranteed be a mess.
When people have finished eating in Sweden they put their fork and knife at four o’clock (though believe me there is some discussions about how the fork and knife should be placed).
Question: In your country, are there any certain unwritten rules regarding eating? And are sounds for example a positive or negative things?
