NO!

No!
I don't want you to say you're sorry!

No!
I don't want you to say you will change, because you won't!

No!
I don't want you to make excuses and say "it's just how things turned out and no one is to blame"!

No!
Don't even think of saying you are convinced you are right and just stubbornly stick to your theories and beliefs, belittling things other people say or do... You would do better to start listening to what others have to say!

No!
We are not little children anymore! People are responsible for the things they say and do, and we both know it! Taking responsibility for your actions is the least you can do to show that you respect other people and yourself, too.

So for God's sake, just act like a grown-up for once in your life!!!

And NO,
this post isn't dedicated to anyone in particular. Though I know many people who would do well to read it and reflect on it a little bit... Come to think of it, so could I... :)
