A lot of doctors or therapists think that people who are multiple are so different from singletons that they have to become singletons instead. They're sick because they're different, and in order to stop being sick, they have to stop being different. They do that through a process called integration, which is kinda like smooshing people together into one person.
Mommy says that forcing integration is like asking me and my brother to smoosh ourselves together into one person! Ewwww! That wouldn't just be icky -- it would be really hard to do. Mommy says she has that much trouble thinking about integration also.
However, sometimes Mommy says that two people in her head get so close together they can't be told apart anymore -- sometimes they even appear to become one person. Sometimes that happens only for a little while, and she calls that "blending" -- kinda like shaking oil and vinegar together to make salad dressing, I guess. Other times it happens for a really long time, maybe even stays that way, and she calls that "spontaneous integration" -- spontaneous means it just happens, that no one made it happen.
Mommy says that her residents can feel free to integrate spontaneously if they want to, but she's not going to allow a doctor to force them to integrate. I'm glad about that. It sounds painful.
