We painted their toe nails for the first month but even after about a week could tell them apart pretty easily. Their position in the womb and the birth means they can have quite different head shapes from one another. Also as another comment said, differences in personality are big and start surprisingly early.

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.

he was the second sperm that entered the egg

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

Yeah was going to say, one or the both of them is going to have a 'tell' right from birth - head shape, a birth mark, hair differences... something.

That's pretty impressive. Having twins sounds awesome.
