A mutually agreed place, dress code, drinks ( Coffee, tea or latte with cake), and walk somewhere pleasant outdoors.
A bit like yesterday; arranged a time to collect from a pub near to their home, drove to a local town, found a good parking spot, walk by the river, explored a castle together, had a latte & cake, walked by the river, sat and talked, walk back to the car, drove to local town that is good for "eye tests", then dropped my friend of at their house, and I drove home. A good day was had out & about in the sunshine.
Looking forward to our next meeting.
