Since I'm a twin I can ask annoying twin questions. :)
Do you and your sibiling experience "weird twin stuff"?
We don't really, but there have been a few times when we have been in separate states, and she knows when I'm upset, and will call me. It has not really worked the other way around though. If i'm sad for no reason I think "ooh maybe Becky's upset" and I call her and she's fine. But sometimes she's sad and knows it is because I am sad.
That's about it for weird twin things on my end. Anyone else?
