The worst thing about e-mail is that you can’t interrupt the other person. You have to read the whole thing and then e-mail them back, pointing out all their mistakes and faulty assumptions. It’s frustrating and it’s time-consuming. God bless phone calls.
When you're with your family you're with them and when you're working you're doing that. I definitely try to separate the time when I'm working and when I have my personal time.
