I was in an almost empry carriage on a train when a youth came and sat opposite.
He started playing his 'music', which was far from melodic and was very irritating.
How to deal with this vegetable?
Well I had recently read a piece where someone had been in a similar situation and started to play some classical music. The irritating individual was himself irritated and moved down the train.
So I deployed this tactic, what have I got to lose? On goes Swan Lake.
Sure enough the vegetable started to get annoyed. "Turn it down", he said.
Up goes the volume.
He asked me several times before he got the message that I wasn't going to comply and wandered off.
I was amazed that this tactic worked, but it did and I would recommend anyone to use it.
