Once I saw a funny picture.On the picture we can see a mother hen invites a tutor-a goose

teach her baby chicken to swim.It is known to all that birds like chickens couldn't swim at all.

But the mother hen wants his baby to learn to swim followed the tutor.We can imagine the final

result.

Nowadays, many parents are treating their children like a mother hen.They expect that their

children to become famous while they grow up.However, they don't know about their children's

interests and advantages.So they invite all kind of tutors to teach their children what they dislike

and they are not good at.Finally it does harm to their children.
