Springlike Autumn! How do you see the world? Do you think that every people see the world the same? Have you ever thought that maybe there are someone who see the world in different colors? My Dad is color blind. Last night when I was talking to my Dad, I noticed he see brown as green and I've thought he is red-green color blindness yet. There is an autumn pic at home. "Do you see browns in this autumn pic Dad?", I asked him. He answered: "It's not autumn, this is beautiful pic of spring!!" Color blindness is a disorder inherited disease that the person is incapable to distinguishing one or several colors. It has no treatment. I hope one day scientists may come up with an answer for this disease. Maybe "Misha" would find the solution. :) By the way, what do you see in this pic? Autumn or spring?

I spent my weekend morning with my students. The good students who learn fast, I really enjoy teaching them. After walking around in evening, I came back soon. Next week is a busy week for me, very busy. I'm not sure If I will finish my works or not. As I'm writing this I feel headache. I'm going to rest now. Sometimes, I think that today is a great day, but unfortunately they are the same!

Lions Lions have always been strong. Always a winner. Maybe they have a lot of features that others do not! All they had is power and glory. There's always a catch for them. Sometimes, they do not hunt to hunger. it's just a break. Sometimes, the wounded hunts have an opportunity to be survived if vultures don't headed. Vultures are always hungry. So, the hunt have not an opportunity to be survived! They always attack in groups. Because they have a poor feature. If there is not any lion in jungle, there is not any deer for vultures.
