Precise body language can often enliven dialogue. For example, a character might say, "No, I cannot do that." If she says that while "hunched over and cupping a hand over the receiver" the effect is dramatically different from, say, "glaring down from the top of the steps, with arms akimbo." In three different scenes, take the same dialogue and add tags* and body language--- but, as these tend to be overused, try to avoid "shrugging," "nodding" or "sipping." (1) In a cafe: (2) In an office: (3) On a hiking trail: "It's impossible, you don't want that" "Why not?" "Can't you see?" "Quiet." "Why should I be quiet?" "Shshsh." *For example, "he said" or "she asked". 1, 2, 3, GO!!
