Thank you for such interesting story, I saw that you mentioned that it is a true story and such a problem like homeless and poverty as well as your own experience just caught my attention.
I was looking at that picture of park and you really can see far back on right a bench and that tree that is almost at the level of ground with its branch.
Reading through it is difficult to imagine what kind of thoughts and emotions were raising in Little John, those people sometimes are speechless and do not know how to react to such gesture, they feel themselves not comfortable and embarrassed. It is very satisfying to know how Little John and his friends were enjoying the lunch and I think he is really luck to have such a supporter.
Would be interesting how your story ends, Cheers, @Stef1
