Question:

Money can buy flowers, .......but can not take back the hateful words, why?

Best Answer - Chosen by Asker: money is a human creation....one of importance in the artificial world created by humans..... in that world much of the natural world has become a mere showpiece that one buys....
flowers is one of those things that we purchase as a showpiece (most of the time)

BUT these still remains an aspect of the natural world that money can't buy- emotions, feelings, time...

hateful words once said belong to the past to time... and the hurt feelings they created belong to emotions and feelings....

BOTH of which money can't buy
