daily culture shock

I am Korean. I came to United States about four years ago. Everything was new to me, the way American speaks, talks, and thinks was different. I’d like to share one of the culture differences among many. In my country, if I have something that I have enough to share with, I used to spend it for my friends. For example, I often chew a gum. So when I bought a pack of gum, I used to give each pieces to my friends. So I thought it would be good to give a piece of gum to classmates in Unites States too. I saw one of classmates coming to me after class, so I said “Hey, would you like to have a piece of gum?” she looked surprise and answered, “I am fine, but thank you.” Then, I noticed something different in her responses. Then I was learned that it is little bit awkward to give my stuff to unfamiliar people for no reason.  

this is me :D
