My deadly trip to a local nursery

Along the path of life, we must go into nature.  My idea of a nature walk is a nursery where trees are in pots as God intended.  So doing my outdoor safari in Oklahoma with my mind set on a climbing rosebush, I approached the nursery. An elderly woman gave me the tour of her roses and the best type of bush for me.  Suddenly, she screamed and ran up a set of stairs. 

"Snake" she screamed.

I froze where I stood asked calmly, "Where?"

"Wrapped around your legs."

Quite honestly what happened next, I cannot explain.  I was airborne.  I rose from the ground and joined the cowardly old woman on the stairs, as the poor creature slitherd into a near by fountain.  A man showed up with a shovel and beat that poor old snake to death.  I cried.  The old woman explained that snakes come to nurseries to get the water during a drought.  But why my legs?  There were many other legs available.
