March Filler: Mistake

Recieved a e-mail poem by mistake:

If a barber makes a mistake,
it's a new style
If parents makes a mistake,
It is a new generation
If an engineer makes a mistake,
It is a new venture
If a doctor makes a mistake,
It's an operation
If a politician makes a mistake,
It is a new law
If a scientist makes a mistake,
It is a new invention
If a tailor makes a mistake,
It is a new fashion
If a teacher makes a mistake ,
It is a new theory

If a student makes a mistake,
It is a mistake!
