Do you like sushi?

I like Japanese food,for example,tempura and sukiyaki. However,I am not a sushi fan. I have a friend who works part-time at a sushi bar. The other day,she asked me to come to eat sushi there,but I declined sayiang "Sorry,I don't like sushi." Then she was very surprised at my words,and said "You don't like sushi?!Are you Japanese?You are out of common!" Really?All Japanese like sushi??It's impossible!However,I have never met Japanese who don't like sushi before!Maybe I am out of common...
