so it IS a far stretch for a person to assume pressure pushes things out? oooooooo-kay
Besides, your buddy didn't say it would move in. He said it would, "HELP you open the door". The door opens in.
So you keep stressing that the door opens in - you write that over and over and over - yet you fail to understand why someone would complain that a writer on this subject wouldn’t drop that interesting little factoid in their article???????
