Yeah dude because 4 and 5 year olds are YouTube's target audience!ANYONE who lived through 9/11 is going to tell their kids about it, assuming they have kids. It's documented in history books already. It will be the subject of tests in the future, assuming it already isn't. Posting a video on YouTube telling people to remember 9/11 isn't heartwarming - it's insulting, because it implies that our memory sucks *that* badly.
