Skimmed Milk

So many movies I've watched in English, so many sitcoms I've enjoyed, so many books I've read and never was I to learn about skimmed milk. Or semi-skimmed milk that is, for that's what I was actually looking for in the supermarket the other day.

You never have two fictional characters arguing about whether to buy skimmed, semi-skimmed or full milk. Or that gentle conditioners are best for sensitive clothing and that a free range chicken must be a happy chicken. These are unnecessary details not worth mentioning. They don't really push the tension in a story. But believe me, they push mine in real life.
