Calls From The Bathroom
You know where you stand with someone when they return your phone calls from the bathroom. I thought the calls from the car on-the-way-to-somewhere-else were bad enough, with the signal cutting in and out. Or from the garage out of hearing from family members. "Seinfeld" immortialized the "cellphone and walk and talk" as not polite or courteous; this makes that seem like proper etiquette. It helps one crystalize where they stand on the relationship totem pole.
