As usual, everyone has done a great job of covering this topic this week. I'm going to go in a slightly different direction.
When my characters are stressed emotionally, I've given them some habits that (hopefully) outwardly betray their inner turmoil.
Sharlie in This Time for Always twirls the ends of her hair around her finger.
Jessica in This Can't Be Love bites her lip. Zach went out and chopped wood when guilt over kissing Jessica consumed him. (He couldn't help it...when she bites her lip it drives him crazy...in all the right ways!)
After a difficult law case, Amber in "This Feels Like Home" decides to escape the city and visit her cousin in the country.
Erika in "Family Secrets" bites her fingernails. (She also opted for a late night ice cream raid of the refrigerator! Something chocolate-y of course...)
Heather in A Christmas to Remember ate entire bags of Doritoes and Double Stuffed Oreos after her cheating boyfriend took his secretary to Jamaica.
I plan on adding drumming fingernails, kicking the foot crossed over the other leg, or toe tapping to future characters.
Until next time,
