My sis and I have certain dynamics where we'll begin acting like different people or characters. Mainly characters. We're Shawn and Gus, Murdock and Face, Gibbs and DiNozzo, Phineas and Ferb... I mean, individually speaking, we're not all these characters, but when we're together, we're so in sync that we've been asked if we're twins (we also pull a Dipper and Mabel every now and again). But just now, we were Tony Stark and Bruce Banner. And then we realized she was wearing a purple shirt, and I commented that she was even wearing his color. We both laughed- then realized that I'm wearing my black t-shirt with a glow-in-the-dark Arc Reactor. I swear, we don't plan these things.
