The wake-up tree.

Some people have a cup of coffee, some tea, or sometimes a cigarette.
But for me, the thing that properly wakes me up
in the morning as I'm out taking Foxy
for his walk, is a firm whack on the head with
the branch of an oak tree
that hangs down over the path
I take almost every day.

It gets me every bloody morning.
