why? why not?

I was buying gas for my car today when the pump-attendant-guy (?, hehe) asked me - out of the blue - "Senyum terus kenapa toh?" (How come you're always smiling?)

His question took me by surprise, I really didn't know what to say, so I answered: "Abis gimana lagi?" (What else am I supposed to do?)

it's funny.. in a lot of cities.. people find it a little strange/unusual when you smile/look happy most of the time.. but they think it's normal if you don't smile/look serious most of the time..

shouldn't it be the other way around?

no one's life is perfect.. mine isn't.. and i don't smile all the time of course.. but when we wake up every morning, we each have a choice.. =)
