why the world is crazy

so there was a terrorist attack in london and as i am traveling i barely know anything about it but i feel sad and scared and overwhelmed. there's a cat shelter where you can pet cats and leave a donation, and i went today and the guy there was telling me that pot is the reason things like this happen, b/c apparently the terrorists ancestors were smoking weed and messed up the gene pool. okay. anyway i hate the way this world is, i hate that sort of thing, and being from new york, it scares me even more.
