I dont see how you can take the events of 9-11 so lightly, wow those pigeons crashed into windows. Its not funny, in fact its a bit saddening that even the creatures of this planet resemble sometimes events or things of the sort like that. Even a year later, 9-11 should be taken even more seriously than just a

at something ironic as birds crashing into office buildings and skyscrapers. Yes time goes on but I hope this wasnt amusing for you.
Edit: sorry there I let my emotios get the best of me. I really just get emotional on a topic about 9-11 because there is always much hatred and sadness involved. I just thought It was ironic that nature can mimic really the actions of a few just without the damage. Atleast not physical but mental damage.
