Since 2000, I have worked off and on as a cater-waiter for any number of rich, Jewish families. And one thing I've always noticed is the ornament hanging outside their front door. It's called, MEZUZAH. I wondered what this ornament was, and over the years, have been told a couple of different meanings. Well, leave it to YouTube to set me straight on the topic. -- I'm not Jewish, but I think I'm going to go out and get me a couple of these for my front and back doors. If the homes I've worked in are any indication, this ornament does indeed seem to watch over some incredibly productive people and their beautiful homes.
