...What I finally to do was to copy other people.I quickly looked around the customers who sat next to me.I found that they all used knives with left hands and used forks with right hands.So I did that,too.And then,I saw a man just sat there use the largest knife to cut the beef and started at the outside and worked in.I learned to copy him.Then I have learned it,too.So this problem have solved quickly.Now,I find that whatever how the problem is big,there must be a way to solve it.
