Recently, I have come to assume that any call to my landline is from a telemarketer or an automated call from Terminex, letting me know that our regularly scheduled pest-extermination service will occur on its regular schedule. So I usually ignore my home phone.

Now we're e-mailing and tweeting and texting so much, a phone call comes as a fresh surprise. I get text messages on my cell phone all day long, and it warbles to alert me that someone has sent me a message on Facebook or a reply or direct message on Twitter, but it rarely ever rings.

I want to let my friend Buster know that I would like to have dinner with him tonight. Does Buster work at home? Then how likely is he to have his cell phone on? Is he one of those people who only turns on his cell when he's in his car? I hate that.

I have no idea how to get in touch with anyone anymore. Everyone, it seems, has a home phone, a cell phone, a regular e-mail account, a Facebook account, a Twitter account, and a Web site. Some of them also have a Google Voice number. There are the sentimental few who still have fax machines.
