One element that is often lacking from conversations between characters is emotional contagion. Panic breeds panic. Self-doubt can infect others. Laughter is contagious! Think about it when writing your novels. While each character will react differently, it's easy to be absorbed in someone else's anger and to start responding in kind. Even burn out and engagement can spread throughout work places ... why not between team mates?
Have you ever used emotional contagions in your novels?
