Things that are considered rude in S. Korea.

These are just some behaviors or things I think are very important to know before going to Korea or into a Korean home. I have personally learned this information or experienced these things during my visit in S. Korea over the years. They may or may not be correct being this is from my point of view so please bare with me and let me know if it is incorrect. 

Rude behavior  in general.

• Do not walk into a S. Korean home with your shoes on. Always take your shoes off before entering someones home. Traditional restaurants also require you to do this as well. So if you see that the floor is raised at the entrance and there are rows of shoes at the entrance, take them off.. This is to keep the house or restaurant clean and keep dirt from being tracked inside. Even if you think your feel are to smelly to do so, take off your shoes. S. Koreans take this very seriously.
• Talking very loudly on the bus, subway, in someones home, or in a restaurant. Use your inside voices in places like these because sometimes you will be told to "Shhh." others. 
• Staring into someone eyes. This is considered to be aggressive behavior and very rude. I am not saying to not look at the persons face but try not to make to much eye contact. In America when your parents want you to listen and tell the truth they force you to look them in the eyes while doing so... You don't have to do that here.
