I read an anecdote some years back. You can find it here.
Anyway, it goes something like this.
A man was drinking with his buddies at a local pub. On his way home, he and his buddies decided that they needed to find a snake to put in the aquarium at their pub. So they found one by the side of the road.
The snake that they found was one of the most deadly poisonous serpents in the world. The man picked it up with his left hand because he “was holding his beer with the other hand.” The snake bit him.
He put the snake into a bag and his buddies started to drive away. For reasons which are unclear, the man continued to put his hand into the bag. The snake bit him over and over – a total of nine times.
He ended up in the hospital; and according to all accounts, he is lucky to still be alive.
Moral of the story: Some people are like snakes. They only want you close so they can continue to hurt you. Wisdom would dictate that at a certain point, perhaps you should quit putting your hand in the bag.
10 Cast out the scorner, and contention shall go out; yea, strife and reproach shall cease. (Pro 22:10 KJV)
10 Reject a divisive man after the first and second admonition,
11 knowing that such a person is warped and sinning, being self-condemned. (Tit 3:10-11 NKJ)Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful. (Psa 1:1 KJV)
My Only Comfort 
What’s even worse is when someone takes your hand(s) and insists on putting them back in the bag, over and over again.
Yes!
Heard this one. A guy walked home and saw a deadly, but frozen, snake in the road (it had snowed unexpectedly and had caught the snake unawares). So the guy took pity on the snake and took it to his home and placed it in front of the fireplace.
When the snake came round, he bit the guy.
“Hey, I saved your life,” the man said to the snake.
“Yes, but when you picked me up you KNEW I was a snake,” answered the snake.
