PHONE ARE OUT

One of the joys of working in a large organisation is the occasional email from people who clearly are not used to typing, or probably even writing. For example:

PHONE ARE OUT
I WILL PUT MOBILE ON AS IT AN EMGENCY.

It reads like a ransom note. Perhaps he's a kidnapper in his spare time. I really don't understand why some people are incapable of writing in lower case. Do they hold the shift key down accidentally with their huge knuckles as they type? Or do they engage Caps Lock deliberately so they don't have to bust their brains working out where the big letters should go?

I know what it is. The Gumbies have finally learnt how to use email.
