I'm not going to be more sensitive
Why won't you be sensitive to others?
People get pissed off easily when I'm not sensitive enough for them
That's right. No one requires you to be sensitive, but it's important to respect and have empathy to others. Being insensitive is ultimately disrespectful.
I don't know what you are so worried about.
I'm just saying you should have some empathy to people. If you remain insensitive to others they will not care for you either. you should spend time with people you know and get to know them more in order to develop empathy.
