I agree. Some may think it’s boring but if you have never met each other a walk in public is a good start. It’s low stress for both and somehow talking feels very natural while walking.

You can plan a circle-route to return to the start. If you’re enjoying yourself, you can sak if your companion wants to continue walking or go for a coffee/drink. It gives them an escape route if they’re not feeling it but if they agree you know that they’re probably enjoying themselves!
