A simple idea for a complex world

Problem 
Some years ago, I spent some time in Vienna and visited a wonderful park.
I was struck by the many lonely people sitting alone on a bench, or walking,
enjoying the beauty of the park, but visibly lonely.

Just two days ago, I was in Taiwan and went to a wonderful park there too.
Exactly the same scenario was seen

I think there are far too many lonely people.

Idea 
Why not we do something creative that could bring them together,
not for a date, but simply for a talk or walk with a friendly companion.

If we could try to have near the entrance of the park a few benches
which are marked or color coded as benches on which people sit,
who would not mind having a friendly talk with someone else or
have a walk through the park with someone else.

There may be different coded benches in the park for people who
prefer to enjoy the park all by themselves.

Anticipated result
When a new person enters the park and feels like talking or walking
together with a friendly companion, he could pick someone from the bench
or take a seat on one of the benches waiting for a friendly companion to enter.

If a creative approach like this would solve a bit of loneliness for just
a few people every day, it would be worth already the small investment.
