so this is what i end up getting from 3 minutes on the roof. i see both ends of the arch of a rainbow (apparently, you could see the whole arch before but i was too late). and there were two rainbows (see picture on the right... if you look really closely, there's two rainbows). and then i turn around and there's a beautiful view of the sun setting. wow... it's made my day. now back to the essay that i haven't worked on all day...
