I hate that it has become acceptable to "do things" on this date now. I am actually a victim of this myself, having attended a baby shower this afternoon. I hate it, and in fairness, I discouraged the date when we were scheduling.
I just feel as though this country is forgetting. It's not a matter of "letting the terrorists win." It's a sign of respect for the 3000+ individuals who lost their lives on Tuesday, September 11, 2001. I find it very disheartening that I cannot even find a conclusive number online.
NEVER FORGET. It is not an option.

2974, RIP
