"America" ?

Lately, I am thinking what my America experience mean to me in the future. Beside my education degree, where will those people and things I met and saw be in my life. I began to conclude that Americans are very bad of making connection and keeping in touch of people. I become very sad about it, and confuse my future. I start to think I should finish my degree asap and go home. This week, my life become miserable and desperate.
