I've come to understand that mastering the greeting is something that every student can do successfully, and that gets my foot in the door to foster a more meaningful teacher/student relationship. Others notice, as well, and suddenly these kids are more personable, more respectful, more enjoyable to be around, and in the long run, more employable.
It's exciting to see that our school district is adopting this as an expectation. Soon, if teachers teach it and expect it, our community will notice a transformation. Community leaders will recognize the change, the respectful culture that all started in Room 404 (OK, I probably shouldn't take credit for inventing the handshake, but I can truthfully say that Hoggatteers are a step up on the rest.).
