What I have been ignoring...

They may forget what you said, but they will never forget how you made them feel.

I think I am not a nice friend since secondary school. I have been going through things alone, without really having a good friend. Maybe it's because the ways I have been acting makes people feel unapproachable. Maybe I have been showing that I am such a independent person and I never rely on others. I may also be very stingy about everything, feeling people should treat each other the same way as they are treated. And, I think the word "sacrifice" is a word which I have little understandings...
