I know being understandable and helpful also hurt us sometimes.

I know when not hurting your friend you hurt yourself how it feels. Sometimes we understand or maybe just try to stay quite to make someone else happy. 

When we understand our friend that they don't want to talk or go with us. We are hurt but we stay quite. I know when we try to understand and help our family we still don't reach their expectation and that hurts. 

You know sometimes asking them why? saying them no isn't bad too.Not hurting them but not hurting yourself too is not bad. You know sometimes not being understandable is not bad too.
