After my wife and her former best buddy, another Air Force wife, were separated by a move that posted one husband on the opposite coast, the telephone became their chief means of communication. When our phone bills showed astronomical increases, the other spouse and I sought relief. Since we both owned computers, we encourage our wives to use electronic mail. Now they call on the phone to let each other know that e-mail was sent, then call back to confirm that it arrived and have a conversation about the contents!
