Umbrella - Pain

With a black silk umbrella
On a rooftop one day
To put physical laws on
Temporary delay.
Goggles on and my shoes tied
Thumbs upturned for the big ride.
I'll step into a soft glide
To the earth far below.
Off I went and down I fell
Like a missile shot to hell.
Umbrella snapped in three,
You're a simile for me.
