Generally speaking, people who open cans from left to right have a strong sense of responsibility. Once they decide, they will stick to it. They are kind and popular in dealing with people. On the other hand, they can hold on to themselves and look down on the world. People who pull from right to left are pacifists and can live in peace with anyone, but they are not good at being alone and can't stand loneliness. At the same time, such people are more willful.
