Is it because my senses are too sensitive? And I am very easily annoyed with typical Singaporeans' behaviours?

Sometimes, some things, really, are not meant to be said out. Keep it to yourself.

And also, some things are not very nice to say it to your friends or colleagues. 要察言观色.

What you want to do? What you are thinking? What you want to say? Sometimes, it is better to keep it to yourself. In my opinion, people, including me, will judge for whatever things you say. Judge as in, grade your first impression.

But sometimes, it is really annoying to see such comments.

So, I am a person who never likes to be known for whatever person I am. Err, well reserved person. I won't say much or comment much on things. And be a quiet person for whoever I am. Well, I don't know if others judge me. I really don't know. But if you do, then, it doesn't really bothers me. But I keep myself afar from people whom I have first met. But, knowing me for long, you will definitely see my true colours. Hee Hee!
