So the father gets on the donkey.
A woman says, " you are not very kind. You ride on the donkey and your little boys walk! "
So the father gets off the donkey and his son gets on the donkey.
A man says, You aren't very nice to your father ! You ride and he walks ! "
So the father gets on the donkey and sits behind his son.
A woman says, is that your donkey ? Are you crazy ? Two people ? You are very heavy! the donkey is nearly dead."
So the father and son gets off the donkey.
A man says, Are you going to the market ? then carry the donkey! it is very tired!
