The mind is strange thing; well mine is anyway.
During my recent trip to South America I would have the hotel television on in the background before bedtime and in the mornings. Mostly I sought out the BBC World Service for the latest news. That service is very fine but it can get a bit repetitive at times. Often in the evening I would seek out an English language movie as an alternative all of which carried subtitles in the local language (Spanish or Portuguese, as applicable).
Despite the fact that I cannot read or understand either language my eyes would constantly be drawn towards the subtitles notwithstanding that all I needed to do was listen to soundtrack in my own language.
