Punctuation: A sua importância no inglês

An English professor wrote the words :
"A woman without her man is nothing"
on the chalkboard and asked his students to punctuate it correctly.

All of the males in the class wrote:
"A woman, without her man, is nothing."


Are you ready for this...........?

All the females in the class wrote:
"A woman: without her, man is nothing."

Punctuation is powerful.
