I think we`ve all been kind of... everyone`s been hurt, everyone`s felt loss, everyone has exultation, everyone has a need to be loved, or to have lost love, so when you play a character, you`re pulling out those little threads and turning them up a bit.
I think of marriage as a garden. You have to tend to it. Respect it, take care of it, feed it. Make sure everyone is getting the right amount of, um, sunlight.
