When people mourn, they don't go to a grave, circlejerk, yell about how much they love their relative, and then yell at everyone who tells them to shut up because it's been 10 years and while they're free to mourn quietly it's annoying as stuff when they do it really loud.
Like chef said earlier, this is the day America gets together and cries and it pisses everyone else off.
On a slightly different note,

Did you know that the passangers risked their lives to save everyone else's.
That flight was going to be bombing the Whitehouse, as they suspect.
But if your gonna be a gaint richard face ass hat, and disrespect the dead, just because it happened years ago.
meany poo-poo face! yes I did know that, people do that all the time.
Something tells me that yelling is the only way you are able to get your point across. You seem pretty pissed off about this whole thing. Go to 4chan and share your opinion. At least there you'll have a bunch of other guys who will continuously agree with you.
Well, yelling is the only way to get this particular point through your skull.
Do you love someone who died?
If so, do you mourn them?
If you don't, you don't love them.
IE: Wizzeh doesn't love anyone.
I don't KEEP MOURNING for 10 years. That is considered a PSYCHOLOGICAL DISFUNCTION.
