He thought the old lady was so kind – until he discovered her secret

So I was sitting on the bus just reading a book when somebody tapped me on the shoulder.
I turned around and saw an old lady. She said to me, “Sonny, would you like some nuts? I’ve got a couple hazelnuts and almonds if you’d like.”
“Sure.”, I replied.

She gave me a handful of nuts and went back to sit with her friends.
“What a nice lady”, I thought, while happily munching on the nuts.
A few minutes later, I felt another tap on my shoulder and there she was again, offering some nuts. I gladly accepted and she went back to her seat.

After about 10 minutes, she tapped me on the shoulder, once again offering some nuts.
I asked her, “Why don’t you eat them yourself?”

“Because we’ve got no teeth”, she replied.
“Then why do you buy them?”, I asked.
“Oh, we just love to suck the chocolate off of them.”
