When you lift the phone you normally say Hello... Do you know what is the real meaning of Hello? It is the name of a Girl..! Yes it is. Do you know who this girl is? "Margaret Hello" She was the girlfriend of Graham Bell who invented telephone. His first word on his phone after his invention was "Hello". That practice of starting the call with Hello still continues. One can forget the name of Graham Bell but not his girlfriend. That is what he did for his beloved. Perhaps it is no less than the work of Taj Mahal.
