Funny story that just happened this weekend. We kept a landline until two years ago, partially because it was cheaper with the bundle, partially because we have four kids and it was almost necessary to have a central line for all sorts of things. But we changed internet providers two years ago and it wasn't bundled to have it and pretty damn expensive, and at that point three of the four kids had cell phones. So we dropped it. Haven't really missed it. That central line actually got annoying because none of us checked messages or used it and then we'd miss things tied to it (a long time it was our main school number for example).
This weekend I took my kid to early baseball warmups and somehow took my wife's and my phone along with us. He forgot a piece of equipment and when I tried to reach out to her I realized I had her phone. Wanted to let her know I had her phone and to bring the gear and I couldn't reach her. No neighbors around, my oldest two kids are not home. I was at a loss. Texted one of my oldest kids and he was like, home phone? Um, we haven't had one for a few years. Then after the kid I was with was warming up, he was like, home phone? Sheesh. But that was the only time in two years I can really think of that it would have come in handy.
