It’s antisocial to leave your phone about so it disturbs other people while you’re gone. It’s a mobile phone, take it with you if you need to receive calls or messages. If you don’t need to receive calls or messages and want to leave it somewhere, put it on silent.

Surely it depends on where you leave it?

Leaving it ringing for hours in a crowded office is obnoxious; leaving it on a side table in your house while you do some chores is totally normal.

And if you're at home by yourself?

Then it doesn’t disturb other people, does it?

Just referring to around the house or my shop really. I leave my phone just lying wherever, texts still come in. If it knew I wasn't nearby and I left it on the dining room table at home, at least it wouldn't buzz to disrupt the rest of my family.
