A pretty lady is standing on the side of a bridge, looking over it and thinking about jumping off.
A homeless alcoholic man comes up to her as he was walking nearby.
The lady notices the man coming and says: "Go away! There's nothing you can say to me to change my mind, you cannot help me."
"Well, if you're going to kill yourself anyway, why don't we have sex? At least I'll enjoy it" replies the man.
"No way, you're disgusting, go away."
The homeless man turns and starts walking away.
The lady thinks: "Is that all you were going to say to me? Nothing more? Won't you try to convince me that life is worth living that I should not jump off? Where are you going?"
The homeless man thinks: "I have to make it down to the bottom. If I hurry, you'll still be warm."
