I'm not sure I even want to register on this, but while perhaps a lady to pine over may be a good bonus, knights are overly romanticized, indeed while most professed a devotion to god, and perhaps some were "perfect" knights, there were more that we're not. So no lady required, many served perhaps, but not a requirement to be a knight, perhaps a good virtue but these were men, and let's say that modern ideals today did not apply....
