Oh god, not just phone calls, but mail, too. And they make some weird connections. I once got a credit card offer that was addressed to me and a woman who's name I did not recognize. It took me a few minutes to realize that she and her husband ran the ISP I used. I was the business contact for my domain, but she was the technical contact since she was at the hosting company. Luckily my spouse is a very understanding person! She was like, "Why are you getting credit card offers with this other woman's name on them?"
