The guy who never learns Torah and never wears tefillin has nothing to be ashamed of on Tisha B'av. He can stand, unashamed and equal, alongside all the other Jews who also aren't learning or wearing tefillin on Tisha B'av.
The guy who doesn't greet because he's depressed or ashamed can stand together with the rest of us on Tisha Bav. And so can the guy who doesn't groom. On this day, none of us shave or shower or wear fine clothes.
If Shabbos is glimpse of Gan Eden is this a glimpse at death? All of us equal, unashamed of our shortcomings, without our clothes or our personalities or our adornments or our learning to hide behind?
