In Peruvian culture when people have to introduce themselves to the someone is very normal that they kiss each other as an apreciative way, or kiss and hug when they are friends. This is very weird in American culture; the first time that I got here I felt very uncomfortable many times because I kissed people when someone introduced them to me, and some of them looked at me as if I was doing something inappropriate, it was very difficult for me to stop doing that because it was the way that I get used to greet. However, it took me some time to get used to some American costums. Now I already know that I just have to shake hands when I have to greet someone.
