Doodling on the phone

Doodling.

This is something I've always done while on the phone and I have absolutely no understanding as to why. But apparently I'm not alone. Do a search for "doodling" and "phone" on Google. Some psychologists suggest that it helps improve concentration. But I think there is more to it. Maybe our brains haven't caught up with technology yet and while on the phone we try to compensate for the lack of seeing each other face to face?

I had a long talk yesterday with a dear friend who is going through some hard times and this was my doodle while talking to him.

Are there any other doodlers out there?
