The one thing you do more than anything else when you build an airplane is walk around the table. You walk to the other side to set a rivet...wait, where are the Cleco pliers?...at the end...set the rivet...oh, the bucking bar I want is on the other side...where the hell is my coffee (take rivets out of mouth before drinking coffee), how does it look from the other side...I'm wearing a groove into the floor.
