Weird smile out there

Most people here don't feel the same way as you do? I agree. In Taiwan, perhaps it's part of the culture here, people got to live with others' respect-free look shooting from every corner. That also explains why ones show their interrogatory look during your walk on street, usually with both eyes staring at you, but doing nothing meanwhile.

Someone curious might show weird smile around, but sometimes with angery eyes also possible. However, it's no harm mostly. Most of the reasons are, people are shy to speak up and nervous to greet you. That's all, that's us.

Take it easy.
