WHAT DO U TALK ABOUT IN THE TALKING STAGE

asking for a friend btw cause i’m useless but she’s talking to this guy she’s known of for quite a long time which she says makes it even more awkward to talk to him. so what kind of stuff would u talk about in a talking stage with someone you already kind of know? she already knows who his parents are, about his family, what he does for work so what can u bring up to start a convo?
