Credit is given where it is due. Positive criticism is never a bad thing. It is aimed at pointing out things in your life that you need to work on to make u a better person. Don't be aggrieved by a honest and blunt truth stating your bad character that needs to be changed.
However you can choose to accept it in good faith and change or take it personal and harbor grudge.
But the fact is sometimes I gotta fuck your feelings and tell u the plain truth no matter how bitter it may sound. And that's how real I can be!
You can love me for that or you can simply hate me for telling u the truth.
