Body language

I firmly believe that body language communicates so much. One of my first week of school lessons is about that - different ways we communicate. It's not just words. Of course, in writing, you would think that it's purely through words. But it's not. The descriptors of how a person moves or how their tone is plays a huge part in things. It can make a person seem indifferent or jealous. The tough part for me, at the moment, is my characters keep showing me different sides. I know what the underlying and overall takeaway from the scene is and how that will play into a later chapter. But, one character keeps bouncing from indifference to outright jealous and possessive. This then causes the other characters to react accordingly. And every moment I think about it, it waffles. To me, this means they haven't quite decided yet what to do. And it's the nuances of his body language that sets everything off. A glare? A dismissive glance? The clutching of a girl's hand? So, I let it play over and over in my head, writing snippets to both - I'd hate to lose the words/tones to either then kick myself later for not jotting it down like I've done on occasion. This, of course, led to me being up at 1:30am this morning and taking forever to go back to sleep - because my brain couldn't reconcile what was going on with them. So, here I sit during my prep period - sleep deprived (maybe 3 hours of sleep) and desperate to get them to settle down. But they have a mind of their own. They just use mine to communicate to the world.
