Always be kinder than necessary?

Came across this article earlier about "10 Relationship Tips Everyone Forgets" and at #6, is something all familiar to me.

6.  Show your loved ones your kindness in small ways every day.

Aesop once said, “No act of kindness, however small, is ever wasted.”  Nothing could be closer to the truth.  Always be kinder than necessary.  You never know what someone is going through.  Sometimes you have to be kind to someone, not because they’re being nice, but because you are.  Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around.

But in reality, is this always the case? That you should always be kinder than necessary. The answer is no. I've learnt the hard way, and more than once, that this does not always happens. Not everyone sees it the same way.

But this is also who I am, and although I could modify a little, I will never change myself completely for whatever reasons.

I am in charge of me.
