Who has a landline in addition to their cell phone?
My husband insists we don't need one, and that our phones are fine. But when I've got a kid who has a non-zero chance of dropping my phone in a cup of water, and I've already personally thrown my phone in with the wash, I feel more comfortable having that extra phone in the house. It's like for emergencies. I may not use it, but I feel safer knowing it's there.
That said, I hate our landline. Roughly 100% of the calls we get on it are from people giving surveys or trying to sell us stuff. And if someone else called, actually for us? We'd never know. Because we finally turned the ringer volume off because we were so irritated by these spam calls. I got sick of my husband saying, "Put us on your do-not-call list!" Because they never do.
Once, many years ago, I agreed to answer a phone survey. I guess I felt sorry for the surveyer, because what a crappy job. She said it would be just a few minutes, and she starts asking me if I saw various movies and how I'd rate each one on some stupid scale. After about ten of these, I was getting a little sick of it and told her so. She said, "Just a few more." Except she kept going, naming more and more obscure movies. Finally, I literally had to hang up on her because she would not stop.
Maybe I'm missing something, but what's the point? What's the point of forcing someone to rate 20 billion movies, none of which they've ever seen, trying to force them to stay on the phone until they completely run out of patience and have to hang up on you?
