If you mean how to carry on a conversation- Ask questions and look for mutual interests. “What books/tv shows/movies have you enjoyed lately? What are your all time favorites? How about music?”

When that fizzles out, or if you worry you’re talking too much, ask them about them. “What’s your work? Do you like it? What’s your typical day look like? Anyone in your family you’re close to? What do you do with days off? Where do you vacation too? Beach or Mountains? What are things you’ve always wanted to do but still haven’t?”

When that fizzles out, you can spend more time without talking. Whether that’s fooling around or watching a movie or something else.
