Unusual
The office door opened with more force than necessary and bounced against the wall.
"Could you just stop talking about it?" Dr. Edith Crawley demanded irritably. "We've already established that I snore. I don't need to know how it sounded in the empty train car."
"It's just that the echoes were such that it sounded like there were three of you with your head on my shoulder," Dr. Anthony Strallan replied, following her into the office and dropping his travel bag next to his desk. "I didn't say it was unattractive."
Edith huffed at him and rolled her eyes. "You complained for three days that you could hear it from your hotel room."
"I was only joking," Anthony protested. "I couldn't actually hear you…"
"It's ceased to be funny. In fact, it never was."
"Fine. Fine. But I really didn't mind you sleeping on my shoulder. Especially the way your mouth, um…"
Edith glared at him. "Um…WHAT? Did I drool? Grind my teeth? Do something socially unacceptable with my tongue?"
Anthony's eyebrows flew up at her last item, and he opened his mouth like he was going to say something, but shut it as if he thought better of it.
"Go ahead and tell me EXACTLY what I did, in embarrassing detail, Anthony. You know you want to. Don't keep it bottled up."
"Well," he began hesitantly, "you sort of… purse your lips. Like you're about to kiss… someone."
Edith stared at him. "Really?" she asked.
Anthony nodded. "The entire time you were sleeping."
"You watched me the entire time I was sleeping?" she asked incredulously.
"Couldn't tear my eyes away." He smiled as she began to flush pink down her neck.
"I'm not sure how I feel about that," she mumbled.
"Join the club."
