I realize now how relative terms mean little, like the following statement:

"She said a normal size is great , but a really smalle one is a complet turn off."
What exactly is normal size, and what is small? I never realized how relative terms can mean little until I live with my mother inlaw. She says that one can eat meat and a little fat every once and awhile. What does that mean? I thought it meant say once every few months, or on holidays. But to her it means every day. She also puts on a 1/4 cup of butter on toast. that is 'a little'. So what does a little or small mean? what does big mean?
