Growing up as an identical twin, I always had somebody to interact with. My twin and I had similar friends, jobs, and hobbies. While we had our own separate interests, we both played soccer, refereed, and hung out in the same friend group. Wherever we went in public, we would receive the “deer caught in the headlights” look.
After people realized that we are actually twins and they were not literally seeing double or hallucinating, they begin to start asking us questions: Are you the evil twin? Which one is older? If I pinch you, does the other feel it?
