Upon a river like a boat,
I saw an autumn leaf afloat,
A yellow ship with golden masts,
It fluttered once and drifted past,
And as I sat beneath my tree,
I saw him and he saw me,
With one arm raised he floated by,
And I'm sure I heard him call out....Hi

Spotted this little chap being blow around by the wind on the pond and he really did appear to be waving!!
