Receive the thing given by other people is better than reject

My friend, Kaccy come my second home where is my rent house in a condol. He bring many delicious durian to my house as he hear that my friends love to eat durian while my friend talking together. But many of my housemate don't want to eat the durian given by my friend. Only a few friend with me eat the durian together...Then Kaccy become scared to talking with them. What the hell? I know Kaccy is very like talking but he become so quiet now.Why the the communication become so bad and I did not aspected???

In the first,what is the advantage if people receive something from the giver?
Of course is we can get something withoout giving money or any cost!!

But.....

Why we reject the things given from other people?
I know many people don't like to receive the things given by other people because they think their opponent no need to reduce their cost to give them somethings. Also some people not receive other people's because they don't wan lose their pride because they think only weak people need hlep and they don't need help.Also consider that the giver must have conspiracy while giving things.

Let try think this event reversely.What feeling of giver will feel if they been rejected while they giving something to a person.

Of course they will become sad and consider that other people don't wan to be friend or don't want to improve relationship between them automaticly.Yet, when I want to give a things to a person no need a very expensive present but is a very strong willpower!!The willpower is difficult to finish charging but once the people reject their regard, then all the willpower has wasted. It is a one hit K.O. and give a mental strike back to the giver.

Now the real advantage for me is can greatly improve the relationship and make the interaction between giver and receiver become more better , harmony and naturally. Everytime I want pay money to giver but they rejected , I will not only say thank you and also said "Next time is my turn to give you something."So we can keep giving things to each other~~No need care about pride or something.
