I think I'm right on this but DH says I am being unreasonable. It makes my teeth itch listening to them, I cannot hear what they are saying because I am waiting for the next inappropriate voice rise. There was one on R4 a few minutes ago and I had to turn her off.
It's bad enough when young people do it, usually with a load of 'like's thrown in for good measure.
God I hate dieting after Christmas!
