Ok..aside from not knowing what 'brown' in the context actually means...two points.
We have heard examples here before of American born, english speaking people never having heard of knitting before. This is an experiential thing and if you had said 'weaving' it may have hit the mark better. How many knitting stores are in that country for example against weaving or rug outlets?
Secondly, a number of high ranking CEO's and American politicians made the point not that long ago that America would fall over without illegal immigrants because they often do the dirty jobs no-one else wants to do.
Tolerance people and understanding that when someone doesn't know something it might not be unwillingness or ignorance but simply because they are not familiar. A number of posters here have spoken about having trouble finding yarn stores in their country. If that is the case then how would people in said country encounter knowledge about the topic of knitting.
