That green smiley's the bastard who did it. Look at that smug grin...I oughta... *waves fist erratically*
Personally, I think the orange one has the closest expression to that of a serial killer. He has those dead-glare eyes, and it looks as if the corner of his mouth could be slightly twitching.
People partic in America ,(+ Britain) tend to go on about smiling. But I dont think I was born as a "natural smiler".Joking , jovial , happy yes. But I mean James Dean wasnt known for smiling and people didnt moan... In Russia , there's a saying "only an idiot smiles all the time". Maybe I inherited that view...Fuck knows. Sure, I've come round to the "smile to disarm , smile to be polite " type of thing. But I think a warm , REAL smile is worth a million "polite" or fake ones..
People do act MUCH nicer when you have a big smile in a lot of countries. Funerals and things excepted ...lol I think its more about getting the right level of non verbal communication with someone. So if that means a real smile ... then great.
