True story. A guy who once was a postman told me this. There was a dog at one of the houses he delivered mail to that when it heard the mailman walk onto the porch, loved to make a run and throw itself against a locked screen door.
The mailman one day crept upon the porch and hearing the dog make its run toward the door, timed its run and then opened the door just as the dog flung itself. He said the expression on the dog’s face as it flew in the air past him was priceless.
A better term for “locked screen door” would have been “latched screen door.”
