For my birthday last year, Jen bought me this awesome book called Ever Wonder Why, and it gives answers to all of those questions about why things the way that they are, but never thought you would find the answer to. Here is an interesting one that I thought I would share.
Ever wonder why a bride always stands on the grooms left?
In the days when men often captured their brides from neighborig villages, a groom had to stay alert to the possibility of an attack by the brides kinsmen or by jealous suitors. This made it necessary for the bridegroom to keep his right hand free during the ceremony to fend off any such attacks. This, of course, meant that the bride had to stand on his left.
