Finsbury Park again

Lovely day for a walk through the park - to the post office in search of a passport that should have been delivered yesterday and seems to have disappeared.
A clear blue sky, and sun shining through the leaves -especially the birches -
Why are the last leaves left the ones at the tip of the branches? Is it a matter of last out, last on?Irresistible to sit in the sun and watch the women and children, men and dogs pass by.
But that was definitely the most insipid cappuccino in all of London.
