Lazy or Genius?

On a scale of 1 to 10, how lazy is it that while at work, I often leave various documents, emails, and applications that I need to print open, and wait to actually print them until I see a coworker walking to the printer to get their own stuff, knowing that they will see mine and then bring it back to me?

I'm gonna go ahead and call it effective time/energy management.  Maybe I should include that on my upcoming annual evaluation?
