Re: Guy I used to know...
They just tutted sternly over the telephone and then forcefully hung up.
One of the many dying arts in this modern world. I only know one person today who has a "proper" phone, and only a handful who have and use a landline.
There is an alternative to the old-style of slamming a phone down, but it can get expensive as it tends to destroy the cellphone thrown violently against the wall.
(Not that I've lost a any phones in this manner.... :) )
