Hold still for her.

You follow the nurse's instructions. Her eyes run over your entire body.

She moves her hand towards your face. You assume she is checking the electrode, but instead she pokes your neck. You jerk.

"Hold still, please."

She prods your neck again, in a different spot. You try to keep still, but move away for her finger.

"Interesting," she says. "Rate the experience for me."

"What you say?"

"Rate your sensitivity on a scale from 1 to 10."

You feel embarrassed that her touch tickled.
