If it matters any, on her website, Christine says that she often emails Mick and Stevie.
Of course, I don't picture Stevie flipping on her PC at the start of the day, and checking her email, but I'm sure someone prints them out for her and she reads and responds to them.
At any rate, there are a lot of ways to communicate with someone, without "talking" to them.
And, for the record, the person I consider my "best friend," is a girl I've known since we were both little kids. We don't talk every day or every week. In fact, sometimes months will go by before we have the chance to talk.
But, we still consider each other our best friend, and we know that, no matter how much time goes between our phone calls, we'll always pick right back up where we left off.
I think
that's a truer sign of friendship than the amount of times you call each other.
