For me I feel like the real move with one of these is to have it rapidly increase the volume instead of turning off the TV because it will probably make the person who is playing it loud feel like people think it is them who is turning it up that much intentionally.
In most cases I think this would mortify them, leading them to turn it back down further than it was originally, or even turn it off themselves since they don’t want to be seen as an asshole and don’t want the attention on them.
Subconsciously I would also think this would prevent them from turning it up again in the future.
Depends on the person though.
Depends on whose definition it is.
Some define alcoholism as a dependence on the substance alone, others define it as a continued use of the substance despite it causing problems for the individual, other definitions require that the user display signs of physical dependency/withdrawal syndrome when no longer using the substance.
Anecdotally, in my experience usually people only begin referring to someone as an alcoholic when they become physically dependent and experience withdrawals when stopping use.
