When your parents can tell when you've been running vs. when you've been building all day.
When the girlfriend accidentally bumps the plane on the workbench and you say its okay but are really checking for dents.
When your mom asks why you pile up kit scraps in a box in the gameroom and you tell her you'll use them later.
When you keep every airplane magazine issue in dreams of having time to build all of the projects in them.
When you cancel a chance to hang with friends so you can finish sanding the leading edge
