"It may just be coincidental, but I somehow doubt it. Come on...a TUESDAY???"

It's a fact of life. The longer humans exist, the more bad things will happen on all of the 365 arbitrarily named and numbered dates on our calendars. With all due respect and sympathies to you and yours, I do believe that you're over-reacting a bit due to the emotional response of this particular date having more meaning to you than all the other dates on which tragedies have occurred throughout history. We can all agree that Pearl Harbor was a sad event, but I think many people would also concede that this is no reason for life to stop on that date every year.

Terrible things happen all the time. Life goes on. It's what our passed on friends and family would want.
