That’s what our older sister calls us because of our unique trait: Irina and I can never be in a good mood at the same time. For instance, if one of us is feeling fantastic, the other is having a terrible day; if I’m enjoying a wonderful relationship with my husband, then Irina has just had a huge fight with hers; if I’m struggling to manage Sasha, Irina is handling her kids like a pro. And vice versa.
Interestingly, we can transmit our moods to each other just by voicing them out loud. Sometimes, we even hesitate to share certain things with one another. This happens with headaches and minor health issues too. You say, “I have such a terrible headache!” and before you know it, she’s complaining about hers, while you feel perfectly fine! I wonder if other twins experience this too?
