If you use speakerphone in public, or hold your mobile sideways to your ear instead of holding it like phone, there should be special camps for you.

Holding phone side ways to ear was when there were nokia phones with loud speakers.

I can think of one inmate straight away, from a few years ago.

This was a young woman sitting on a railway-station bench about ten yards from mine, yakking excitedly and almost non-stop in what I think was Italian. The woman at the other end of the 'phone could hardly get a word in edgeways.

She was sitting upright, gazing straight ahead, 'phone flat on her lap, 'speaker turned well up so I could hear the occasional edgeways word; as if she was trying to speak not to the 'phone but to anyone on a diesel multiple-unit train idling very noisily at a platform opposite ours but about fifty yards away.

I was glad she didn't board my train, or if she did, I didn't hear her.

So, that's basically the deaf you've got it in for, then???
