Operation Ivy - Caution

Caution is a word that i cant understand
C-a-u-t-i-o-n was a word i could not understand
Walked the dog with a real short leash
Turned around saw the dog walk me
Stainless steel and painted glass give me
A pulse like a hammer and a mind to match
No relief no food no sleep
When you're king for a day
You're a whore for a week
I didnt get it then
I think I got it now
Caution my freind
Dont step in the water 'til you know you can swim
