In the park I saw a old grandma pushing a wheelchair where there was an old grandpa sitting. They talked now and then and called each other darling, and it was so warm and sweet.
I walked forward and asked the grandma how could they keep such a good relationship in their long life?
The old grandma said: many years before, he had an affair with another woman, and he want to abandon me.
I felt so confused and asked: how did deal with it?
The old grandma answered: look, I just broken his leg.
I'm freezed and had nothing to say with her, then I asked the grandpa: She had broken your leg, and why do u still call her darling?
Grandpa said with a sigh: I had forgotten her name many years before, but I dared not to ask herbecause I don't want to lose my another leg.
