You didn't remember to Google "Catholic left," did you?  It told you about that for your edification, but you're lazy.  Should've known.  Anyway,  . . . 

Now, having shown two provable acts of senility in one post --- a first for you --- you're trying to conceal them by "educating" me as to why the "Sign of Peace" immediately follows the "Our Father."  How clever.  But again, Jim, we weren't talking about shaking hands at the "Sign of Peace."  The subject was holding hands at the "Our Father."  Remember?  

BTW, I never said that the "Our Father" and the "Sign of Peace" were not part of the same introductory ritual of the Communion rite.  Remember?  So where the basis for saying that "for [me], that is a non-essential element"?  Did you dream that?  Snap out of it, Jim.
