    My best friend is a mirror twin. His brother cried a lot more as a baby. When they became toddlers his brother complained a lot more. Now as adults, his brother still complains and argues a lot more. I don’t understand how they can be genetically identical, have the exact same upbringing, and be so different from the moment of their birth, but they are.
