It´s very interesting that many people come up with one basic conclusion in this networked world: everyone has to provide 24/7 on-call service! If they don´t receive an instant reply on the phone, via e-mail or whatever they tend to become upset. Not so much because there is some fire burning that has to be blown out, but because instant messaging and mobile phone MEANS everyone has to be avaiable all of the time for interaction.
Which is untrue, because with every mobile phone one can switch the ringtone off, leave it in a dim lit corner of their home or simply ignore its presence for a few days. Facebook is good for chatting but aswell chats can be denied. Even the landline in my home is not the red telephone of my life. "The Doctor Is Out", as read in The Peanuts.
