A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

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.

That's not how identical twins are formed. An egg, fertilized from a single sperm, splits into two, creating two people with identical DNA. You're thinking of fraternal twins, where two separate eggs are fertilized by two separate sperm.

Normal: 1 egg + 1 sperm make 1 person

Identical twins: 1 egg + 1 sperm make 2 person

Fraternal (non identical twins): 2 eggs + 2 sperms make 2 person
