1. My cousin had twins, one had a name that rhymed with a color, so she painted that one’s nails in that color, until they grew old enough that she could tell without needing to look.
2. My twin and I aren’t identical but we sure look like it. I’ve always asked my mom this question and she said she knows 100% we are who we are because when we got home from the hospital she kept our hospital bracelets on for weeks. Everyday she would looks us over trying to find any difference in us, any freckle or dimple. Something to tell us apart. And when she found something she took the bracelets off and gave us small little beaded bracelets. And once those got too small she pierced our ears, I had diamond earrings and my sister had pearls. She swears to this day, she can tell us apart with her eyes closed. (Which is totally true. We tested it way too many times).
