Not so fast 别那么急嘛
A pig and a chicken were walking by a church where a gala（欢庆的） charity event was taking place.
Getting caught up in the spirit, the pig suggested to the chicken that they each make a contribution.
"Great idea!" the chicken cried."Let's offer hem ham and eggs?"
"Not so fast," said the pig testily. "For you, that's a contribution. For me, it's a total commitment."
