As I see on the web pages, the word familiar is mostly used for things rather than people. For example although you can get familiar with someone, but most of the times, you use it for "something".
I.e. "how did you get/become familiar with our company" which to me sounds a bit formal.
I need to know, how a native speaker would say the bold part below in natural English:
A: You seem to be too friendly and that's pleasant to me.
B: That would be more interesting to you if you know that we became familiar with each other just yesterday.
Does my sentence sound idiomatic or you confirm my understanding?
A: Guys. I like the respect and mutual understanding between you two. You're really good friends. I like the way you are treating each other. That appears pleasant to me.
B: Thank you. I think it would be interesting to you to know that we became familiar with each other just yesterday. We disn't know each other by yesterday. We met at the gym and made quick friends the previous day.
