Ok this might seem weird, but...
Lets say your having a bad day for whatever reason and the world has you down, who else looks at a picture of Neytiri to cheer themselves up? For me it never fails, if I see a pic of Neytiri smiling it will put a smile on my face no matter how bad my day has been. I think it's because she has such a positive energy and pure spirit that it kinda rubs off on you. The thread "Post your most beautiful pictures of Neytiri" can be a great inspiration when having those bad days
