I'd certainly like to be better at it and I do try but those first minutes a stranger while you are searching for a common topic can be gruelling. I'd rather be introduced by friends who say "you both like X" and go from there.
What excellent advice! My go-to line has been "what's been keeping you busy lately" which is a polite form of asking what someone "does" without making them them I only care what job they have.
