The benefit of a ‘virtual window’

It’s 9 o’clock on a Saturday morning. I start my computer and launch the Skype app. I create a video call with two of my buddies and then get breakfast.
Suddenly I hear: “Hey Jeremy, you there?”.
I pause my breakfast, go to my computer and I see there Kevin, I wave to him and say “yeah, I’m just finishing breakfast, I’ll be there in a minute”.
Kevin nods, “OK, I’ll continue with finishing up my scenario”.
I go finish my breakfast and then join Kevin on my computer.
