I haven’t had a land line since the early 00s. The only time I miss it is when I lose my mobile phone. I check every room, I check under piles of paper, I check the fridge, but I can’t find it.
I no longer let myself get apoplectic. Instead I turn to PhoneMyPhone. Type in your number, and PhoneMyPhone does just like the name says. It phones your phone. A few times, if you want, to give you time to run to the car and check there.
You could also use it to be sure you receive an important call during a boring meeting or a bad date. I’d never use it for that though. Never.
