To put your theory to the test, I'd like to share a similar experience I had with lightbulbs, as line 2 of your theory suggests. We can then see how long it takes before other lines are satisfied before reaching line 6 (the appropriateness theory). Hopfullly suphicient speling misstakes are present to allow others to jump in.. .Why does it take 5 women with PMT to change a lightbulb?. .(shouted) IT JUST DOES OK !!!!!!
