Fountainhead

I must have been
About five years old
When I tried to pass
Under the handrail
While running
At full gallop
Across my Aunt’s yard.
I may have done that
Countless times before
Without a problem,
But I was a wee bit
Smaller then.
I didn’t realize
I was hurt at first,
But I was spouting blood
Like a fountain
And splattered my aunt
Fifteen feet away.
It took seven stitches
To calm my Aunt down.
