From sadness comes joy, from weakness comes strength, from burning horribleness comes beautifulness. 9/11 is a perfect example of all of those. For sadness, it means when the planes crashed into the twin towers and all of those people died. The joy is how we created all of these things to help like websites to help people deal with the sadness or anything else. With weakness, the twin towers were not strong enough to hold up during the impact of the planes hitting. The strength is how we have created a stronger building in replace the twin towers. It can stand an attack and it can get everyone out in no time. For burning horribleness is how the twin towers were burning and the smoke and the rubble. The beautifulness is the monuments that we built out of the base of the towers, and the brass metal carving a wall near the monuments. This is proof that we can rise up stronger than before, never give up even when there is a horrible thing going on, because if you stick around, you will not regret it because we WILL rise up stronger that ever!!
