If you are sincere, send it to me. Don't just say how to reply.

According to your description, if a person says to you, "You are so polite, it should be that I thank you for giving me the opportunity to know you". I think this sentence should mean that you are dating this person. You said "thank you for giving me this opportunity to get to know you" to the other party, and the other party replied to you like this. In this case, you didn't make it clear whether you are expressing a euphemistic refusal or have a good impression on the other party, so you can only analyze two possibilities, and analyze the specific problems:

First of all, if you say "thank you for giving me this opportunity to get to know you" to the other person, which is a kind of euphemistic refusal, then the blind date will respond to you politely, and then you can directly come to him and say: Although I feel that we are still not suitable, I am really happy to have the opportunity to meet you, and I hope to be friends again in the future. The other party should understand what you mean.

Secondly, if your sentence "Thank you for giving me this opportunity to know you" means that you are very happy to know you, you are lucky, but it is actually very simple. We can continue to meet next time, and then meet more, so we don't have to be so polite in the future, and we can gradually deepen our understanding and communication.

In a word, the other person is a polite person. You can express your ideas clearly and politely, and there should be nothing to make the other person unhappy.
