If the other party sends an invitation or a gift, and you need to decline it for some reason, praise and thank the other party for their warmth and friendliness, and express that you are very willing to accept this feeling. For example, "You care about me. I appreciate your kindness! " "Thank you for your kindness!" In this way, even if the other person is rejected, he will still think you are a reasonable person because you understand his good intentions.
