The Heart of a Good Man

I was a rich tycoon who was obsessed with greed.
I wanted more and more money even though it was something I didn't need.
Something happened to me and I'd like to explain how but I can't.
My personality completely changed after I had a heart transplant.
Instead of wanting to make more money, I'm giving money to the poor.
Things completely changed after my operation, I'm nothing like I was before.
I own four apartment buildings and I was a slumlord.
The tenants hated me, I wasn't a man who they adored.
The apartments weren't fit to live in but I had all of them repaired.
In the past, I didn't give a damn about my tenants but now I care.
Before I got my new heart, I was a taker but now I'm a giver.
I closed my textile plant that dumped toxic waste in the river.
I learned that my new heart came from a man who was only twenty years old.
Before he died of cancer, he was the salt of the earth with a heart of gold.
He gave money to charities and always put his needs before the needs of others.
When I got his heart, I also got his personality and I think of all men as brothers.
I don't know how this happened but there is one thing that I do unferstand.
I've become a very good person because I received the heart of a good man.
