For some reason, I rarely use the telephone to talk to someone. Perhaps I am just not used to transmitting my voice electronically. That is why I probably don't answer a call when I know that the caller has not that anything important to say.Past telephone technology required us to answer the telephone whoever the caller may be. Fortunately (or unfortunately?), that is not the case now as owners may now choose to answer or not to answer a call without a feeling that that call is important. Some phones can even ban some owner-chosen callers.
By using caller IDs , the owner of a phone unit does not have to answer the call just to know who is on the other line. Perfect for people who are hiding from someone--your ex, the bank, or someone like that. I especially like this device so that I can answer calls that are really important and not calls from some annoying neighbor. It's funny that they call you when, in fact, they're just next door--not that I like to see them in front of my door, anyway.
Of course, there are still calls that are important and yet we are not available to answer them. Here's where answering machines come in (And don't forget that we have answering machines here at Office1000, too.) Callers can leave a message, so they could tell you what they had to tell you. The downside to this is that even annoying callers leave their annoying messages, too... and you have to leave your voice as some kind of warning message. Oh I hate to imagine callers listening to my recorded voice again and again. It seems so unnatural.
...Which just means that regular offline conversations are still the best. At least, in offline conversations, you get to know if the person you're talking to really means what he/she says--something that cannot be done in online conversation anymore.
