The big heavenly tree

There is a tiny park in the city centre, Piazza delle Poste. It's a big garden, rather than a park, I should say. There are several huge trees and flower beds and the soil is covered with grey oval gravel. There are green benches in the paths and in summer it is a shadowy place for a fresh stop.
Today in the early afternoon I was passing on the lane at the side of the park where it is enclosed by a high wall. There were four young friends having a chat. The tree looked heavenly as the intense rays of the sun enlightened the leaves and filtered through the spaces among the branches. This vision inspired me the words, I don't know if I can call it a Haiku...

The big tree witnesses all,
hopes, friendship and young love
in a sunny afternoon
