Inevitable Fall

I am a joe named bill . . .
I know when I am at top of a hill
because every which way looks down.

Some friends say, "look up, look up!"
but vertigo spins me into looking down
and I stumble like a twice-practiced clown.

Except, I have no practice at all
I am just a baby brother joe named bill
and I am starting to tumble and fall,
not quite deciphering up from down.
