Also, I have to intuit who reads all their emails every couple of hours and who checks them every couple of days, who wants a paper copy to review and who'd rather die than look at anything but a screen, who brings a pen to meetings and who uses a tablet, who shows up without their laptop unless you remind them ten times and who will carry their laptop to their grave in a vise-like grip. I have to figure out who needs a text so they will read the email I sent.
