It's nice now because we have caller ID and answering machines/voice mail, but back in the day, I remember the only way we'd know who was calling was if we actually picked the phone up. Now I won't pick up the phone at home if it's a number with an area code we don't know--I figure I can listen to the voice mail and call them back if necessary. Part of the reason is that our old phone number used to be someone else's as well and I'm tired of answering the same questions about it. Our voice mail announces who we are...but I think some people just don't listen to it and leave a message anyway...I'll say, "You've reached the residence of Mr. and Mrs. Lois Lane. Please leave a message," and some callers will still say, "Hi, can Mr. Smith call me back about his order." Um, OK. Not!
