A man once went into the backyard to play with his children. A few days later, his ankles, elbows and wrists were covered in blotchy, itchy, red spots. The man's wife went to the store and purchased Tecnu, a healing salve that promised to make him feel much better.
The next morning in the shower, instead of applying the Tecnu, the man let the hot, hot water pour over his irritated arms and legs. It felt wonderful and seemed to make things better for a little while. In fact, the feeling was amazing, blissful even. So blissful that he let that scalding water hit his tender skin for a long, long time.
Within a very short time, the Poison Ivy, having had its oil released from the man's pores, spread its blotchy, itchy redness all over the man's body and drove him nearly insane.
The man couldn't stop himself from scratching. He scratched and scratched, until his sores stung and bled. And still the itching continued and the blotchy redness spread.
Next, the man tried not to scratch. He did everything in his power to ignore the burning, itching and swelling... He might poke or slap or rub his skin, but he tried and tried not to scratch it. Eventually though, no matter how hard he tried, he always gave in and scratched. And still the itching continued and the blotchy redness spread.
Finally, in desperation, the man ran to the shower, stripped off his clothes, and slathered the Tecnu all over his ravaged body. Although he didn't feel much relief at first, he continued to apply it every day until slowly but surely the Poison Ivy oil was removed from his body and the blotchy, itchy redness was all gone.
