I used to do this during long travel in planes, buses or trains when I was single backpacker.
Now traveling with my own family is just exhausting chore and I couldn't care less about stranger sitting next to me, I heard enough stories for whole my life since I traveled a lot.
Recently I traveled with my mother to China and she was excited to talk with some girl next to her on long flight, I didn't find any value gained from such conversation and would rather watch a movie (or outside window is that was an option) and find it harder and harder older I get to see the added value.
