Last night a telemarketer called and asked for a Mr. vanGerwen. My husband and I don't share the same last name, so I answered the question truthfully and said that there was no Mr vanGerwen at this number. He apologized and hung up. I still get giggles thinking about it.
The next obvious question, which I was expecting him to ask, was if Miss or Ms. vanGerwen was around. But he didn't ask; he just hung up! Whether you're doing research, interviewing someone or seeking info from a PR rep, always ask the next question. People can't read minds and aren't always forthcoming with all they know, so be sure you've asked from every angle.
