It is perfectly normal to wait for gratitude for the good.
“If you sell it, you sell it!” - everyone knows these lines. They are especially to the liking of those who devalue good and show foreign gratitude. With these words, they bitingly correspond to the confused benefactor, reproaching him for "self-interest." Not only did the person share the last or save someone from trouble by sacrificing themselves. Now he is also mercantile. Calculating…
The brain of a mentally normal person works like this: following an act addressed to someone, the brain expects an adequate response. Predicts other people's behavior. Hit someone - you can get back. Scolded - you may be scolded or cut off contact. Gave candy - thanked. They showed sympathy. It is on this forecasting of someone else's behavior, someone else's reaction that all human relations are created. The whole civilization. If the response is inadequate, we feel frustrated. We are confused. The brain begins to process information and suggest a new strategy of behavior to us.
They gave us candy, but they kicked us or gave us a crack - you can't give candy to this person. They rescued us from the trouble, and then they slandered us - there is no need to help this man out anymore. We pressed a button, and we were shocked - no need to press this button. And if you press, be ready to receive a discharge. Click and run away! If you have time, of course. Or take the blow calmly. Endure. Over time, the habit of hitting is formed, and you will expect it instead of gratitude.
We cannot change the work of a developed brain. This is the way evolution arranged, taught the brain to work that way. Action - response - a comparison of an action and a response. And the resulting reaction makes us either refuse from the act in the future, or expect another reaction: a kick or a click.
So waiting for gratitude is perfectly normal. This is a sign of mental and psychological health. And humility with ingratitude is a sign of a high spiritual development of a person. This is the next stage after comparison. Therefore, there is no need to reproach yourself for the pain and disappointment; this is normal. Now we know that good should be done to this person or to people like him with caution. Wear rubber gloves to avoid electric shock. And immediately run away.
And those who demand gratitude “sell good”. Observers name, observe and exaggerate. Apparently, the translation is far from the original thought of the author. It's okay to wait for a normal reaction. Demanding payment is not very nice, but it is the full right of the one who sells his property. And, too, there is nothing to reproach. People in “helping” professions, such as psychotherapists, sell goods. And indicate the price. Artists, musicians, writers also sell goods. For money. And Omar Khayyam, the author of the poem, also successfully sold his wise thoughts. He worked as a vizier at the court of a wealthy ruler.
So don't be manipulated. You are waiting for an adequate reaction - it means that you are an adequate person. And your brain is working normally. Whether to demand payment for good is up to you. It all depends on you. And not from someone who devalued your good in advance, but accused you of self-interest.
