Notifications started working in the middle of the night last night (well, east coast US time), since I woke up to a bunch of emails. Then they broke again. They started working again at some point in the last couple hours, at least briefly, since I got a couple more review notices... but I've read and reviewed chapters I still haven't been notified of.
Re: Body language...
One of the most interesting assignments in a creative writing class I took was to go to a public place and observe people from a distance. People alone, people in pairs, and people in groups. We were supposed to stay far enough back not to hear them and describe their motions and actions in detail. Later on we took one of those descriptions and had to create dialogue for it.
It's interesting, the things people do. And everyone has their own quirks. Some people might fold their arms when they're upset, but others might shift one foot behind them and lean their weight back slightly, or they might open and close their fists, or put their hands in their pockets and narrow their eyes.
Personally, I prefer to have people interact with their environment or the people they're with instead of just tilting their head or whatever. An angry person might slam a book down, or their glass. They could shove back from a table or something. Someone who is comfortable might warm their hands over a fire, or stretch their legs out and lean back on their elbows. Two people who are involved might randomly touch each other, running a hand across their partner's arm, or brushing their hair back. I'll sometimes include random actions if I want to break up a chunk of dialogue without ending the conversation. Like having someone say something, stand up and put a log on the fire, sit back down, and continue speaking.
Some of my major characters have mannerisms that are unique to them. Maggie will start playing with her hair when she's upset, tugging on it or shoving it behind her ears and pulling it forward again. If she's comfortable with the group she's in she'll pull her feet up onto her chair like
this. Anders covers his mouth when he finds something amusing at her expense and bites his nails or tries to smooth his hair back when he's nervous or upset. Alistair rubs the back of his neck when he's embarrassed or doesn't want to talk about something. Some of them people have picked up on, others not, but it's mostly for me to keep them all distinct in my mind.
