When you say "thank you", it means that you are satisfied with the help or service given by others, and the other party will be very happy to hear it. Sometimes, others serve you, maybe it's their job. If you don't say "thank you", they will never blame you.

However, indifference to other people's services shows that there is an invisible boundary between the two. At best, it is just a professional relationship between service and service, lacking emotional communication between people.

However, if you express your gratitude for this well-deserved service, then their relationship will change, their psychological distance will be shortened, and their feelings will resonate and sing.

When the other party is excited and happy, they will give more care and better returns, so the communication atmosphere will become more harmonious and warm. Communicative psychology believes that there is a "reciprocal interaction effect" between people, that is, how you treat others, others will return in the same way.

In interpersonal communication, don't forget to say "thank you" sincerely when others serve or help you. Saying "thank you" seems ordinary, but it can cause benign interaction between people and become an accelerator for successful communication.
