From my experience in MFWI, I learned many things. 

 First, America is very big country so there are many people from different countries. I thought America is very mixed by many different things. 

 Next, I was shocked by same sex marriage. My host family’s friend were same sex couple. I was interested in this because we can’t marry with same sex person in Japan.

 Like this, there are many differences between Japan and America.
