Old people, Moore College graduates and other technophobes need to hearken to this parable:
Treat your mobile phone less like a doorbell;
Treat your email more like a phone.
You don't need to jump to the ring of your phone: you are allowed to ignore calls, that's what SMS and Voicemail are all about. But you do need to respond quickly, regularly and constantly to your email: don't let it pile up over the course of a few days, after all, you don't need to compose perfect epistles.
