to ignore/unplug the landline?!

[Hudson10]

Inspired by the thread where people don't answer the door. (I do answer the door, by the way.)
The phone though? No, it's usually unplugged. Much to the bemusement of relatives who just cannot get their heads round it and always complaining "your phone's off!" Yes, I told you we don't answer it.
RING. THE MOBILE. OR TEXT.
In this day and age why do we need the landline anyway? It's only full of cold caller crap anyway.

Looks like I'm not the only one who doesn't use the landline then, so not sure why it's such an alien concept to family who insist on ringing it!
If you're going to ring a phone you have repeatedly been told isn't used, you've only got yourself to blame if you're managing to wind yourself up in the process.
