She gives... He thinks not...

She thinks she gives.

But he thinks she does not.

Whose fault is this?

No one's.

Think of it. You are allergic to alcohol (Let's assume you can die if you drink it). Someone offers you the most expensive alcohol. Will you like it?

No. For you, it's nothing but a suicide bomb. This very most expensive alcohol that most people value has no value to you. Can you blamethe person who offers it to you? No. S/he is providing you with the best that s/he thinks.

Yet, just because it has value to him/her, it doesn't mean that you will value it in the same way.

The same case with above.

She thinks she gives all her best.

Whether he appreciates it or not is his personal choice. She has no right to force him to think that he is getting the best.

"Beauty is in the eye of beholder." Whether she is doing her best or not depends on what he thinks or appreciates. Not on what she actually does.

So, don't complain. If you care, provide the other person with the best you can afford. You have no control over whether s/he likes it or not. If s/he likes it, you are lucky. If not, that will depends on you... whether you want to continue or not. 

For me, if I care, I will continue no matter what. As long as I know I am giving my best, I will not complain if the other person sees it or not.

Anyway, love you.
