why is the picture of this category a smiley?

It's easy ^_^ JUst because mylot wants everybody to be happy in life ^_^ Nothing beats being happy in life, and life consists of us ple, everything we do, affects each other in a way or other ^_^ And we can also change the picture from the interest page.. But so far this picture has not been changed and i guess alot of ple likes it ^_^ Or maybe most dunno that they can change the picture of that interest.. lol

I guess it is because this category encourages everyone to be happy with their life..hehe.

it is the one you chose, mine is not a smiley
