My professor walked in the class today and said, " We are going to do a very special experiment today."

He bought 2 plants and placed each plant at the end of the class. Each day, different people were assigned to each of the two plants. What was their job? Easy.

Anyone assigned to Plant A had to scold the plant everyday. Say whatever they like.

Anyone assigned to Plant B had to compliment the plant. However they like.

The students were quite confused but they followed the professors instructions. Eventually after a few months, Plant A died despite us watering it and caring for it as much as plant B.

" So why did Plant A die?" The professor asked

Everyone didn't know how to answer his question.

Our professor smiled as he looked up.

" Words can kill ."

We were left speechless .
