Can you Answer The Phone Please? Do you get annoyed with solicitors?

What is the purpose of having phone solicitation?  Do you think it should be against the law?  Why do we have laws?  What is the real purpose of human beings making up things to control our lives?

Do you answer the phone when you don't know the caller?  Do you prefer to have only a cell phone rather than a home phone?  What is so important that you would pay to talk to someone?  What can a company gain by calling you on the phone?  Are you a sucker for sales calls?
