Why do you lie to pig?

“Hello, pig. Can I ask for your garlic chives?” Cow, duck and twin piggies said.

“Well, now Robert is in charge of them. Ask him,” I said.

All of them shook their head, “Then we don’t want them.”

“Why?”

“Before he was kind and friendly. Now he is mean.”

“What did all of you do to him?”

“We didn't do anything. He changes.”

“If he changes, why does he change to all of you, but not me?”

“Perhaps,” three of them whispered into my ears, “he is trying to take advantage of you.”

I laughed.
