Clouds

Then next time you're in a bus in the afternoon or in the morning, or you have nothing to do in class or at home, just look at the sky, look at the clouds, it has a huge calming effect, the beauty of the sky and the clouds from the ground may not be as good as the ones in high places, but you just find yourself staring at it for a while. Great for stressed people. Try it!

Random side note: We need to talk, you know who you are.
