Twins: How similar are their personalities or behaviors?

I am a boy, a younger brother, and a fraternal twin. We may be different between twins. Since junior high school, we no longer wear the same clothes. Since high school, we have gradually discovered that each other is very different from ourselves. From behavior to thinking mode, they went abroad to study and went to different countries. Two people with different personalities in adolescence have lived abroad for several years. After meeting for a month or two, it seems that only * * is tied together.

When we meet, we will quarrel and even fight, but when we grow up, we will only be nervous, because it may really hurt us, so both sides will consciously control their fists after getting angry. In addition to parents, we used to get along with each other as childhood friends and two high school friends. It is also common for people in our class to pull our frame in high school. I've heard many people ask, aren't you brothers? Aren't they twins? Why did you fight? I just want to say that there is nothing that should or should not be. To put it bluntly, my relationship with him is at arm's length.
