Twins are scary
In middle school I dated an identical twin. It was fun, but I could easily tell them apart.
...
When my mother was pregnant with me, they did an ultrasound and found she was having twins. When they did another ultrasound a few weeks later, they discovered, that I had resorbed the other fetus. Do I regret this? No. I believe his tissue has made me stronger. I now have the strength of a grown man and a little baby.
As many people know, I have twin brothers (somewhere in the 11 of us).
They're proper pranksters, and they spent all of their school life confusing teachers (they're identical, of course).
If I don't have a twin then I really should throw away this half a pendant I've been walking around with since forever.
