As an Asian (Filipino) we generally have inside and outside face. Other Asian cultures have that similar feature.
It's because family honor and reputation is idolized there and it's the basis of a lot of people's ego.
Therefore we overly watch our conduct and try to appear as approachable and friendly as possible. Even look like weak pushovers sometimes.
But many Westerners especially the ones who have had interactions with our military (joint training, exercises) think that we Filipinos are all expert knife fighters and boxers (thanks Manny Pacquiao).
I was even asked at a workplace if I carry a balisong (butterfly knife) all the time like a cowboy carries a gun all the time...
