"a person with whom you are on the same wavelength"

I met this guy on Twitter. Our acquaintance quickly developed because we were interested in the same topic. He shared his experience, and I shared mine. During the conversation, I had a positive impression of the punk. He showed himself to be a very intelligent person. A guy who is happy to help and will never refuse when help is needed. I am glad that I had the opportunity to meet such a wonderful person.
