Loving English, as many rules as I can understand and remember seem important to me, so sometimes I do say, "Thee" and maybe "Thou," but not accidentally. Understanding a rule can help me have more tools. Such an understanding, can help me understand the other guy more too. I try to follow rightly with "who / whom," and with "Farther / Further" too.

There used to be a quiz show, hosted by Johnny Carson, called "Who do You Trust?" "Correct" would have been "Whom do You Trust?" Just saying.
