An interesting video for many reasons, not the least of which is watching Molly Crabapple illustrate the ideas:

I think one of the interesting things about me and Matthew is that each of us can be either introverted or extroverted, but often not at the same time as the other. We swing back and forth like the tides. Which is great for when we as a creative partnership have to perform a particular way, but totally sucks for when either one of us wants to enjoy the other’s company.

That being said, the whole dog/cat metaphor is off in our case.

Iggy is a total introvert.
