She said

Sir please let me go

No, this is not right

What will people say?

You are of my father’s age

No, please, I beg you sir

Even your hairs are white

Prof. said

All girls can bear all sizes of it

So even two-year baby get raped

You are my student so don’t forget

Man's virilty cannot be judged by age

Real age is hidden between one's  thighs

Hence there might be fire below white ashes
