watch this video and telll me if 你 think 911 was a terrost attack

Why would 你 make someone watch this tragic thing on purpose? Of course 9/11 was a terrorist attack, which is why I'm currently afraid of planes now.

The weight of the building collapsing and the shock probably caused it to start to collapse in other places. >.< The weight made other parts of the structure buckle, since, 你 know, a plane just ran into its side and hundreds of tons of concrete and steel framing are collapsing onto the lower levels.
It makes sense. Unlike your grammar.
