That then tells you that you have Really Scared someone? (From a certain reaction on their part)
My favorite thing to hear from a customer comes after my long front room story which ends with my own death....much silence follows.....then I drag one shoe across the carpet (from 15 feet away from them) making just that slight sound (of someone talking just One Step) and when someone screams from this..... I know I have got them!
I never get tired of this!
