I am in total agreement with PH. (However, I have a feeling that this is more of what TIL had in mind to begin with. Am I right, TIL?) To make it a day of rememberance would show the due respect without turning things into the raucous circus/party atmosphere that has come to symbolize other days. There IS something to celebrate...the fact that we remain and carry on. But, IMHO, that is best done by living our lives and caring for our fellow man just a bit more...and SHOWING it in what we say and do. That goes for every day...not just an anniversary observance.
