Actually this one is quite fun.
One year my youngun was talking to some guy in Kansas I think...can't rermember the call but anyway he was giving out "Corduroy" as a color. Of course, an argument was had about Corduroy not being a color yadda yadda...
Then the guy said he was blind and could not see colors but used textures instead.
Shut my kid right up..he took the exchange and we carried on.
Have fun...some of these kids are quite good.
