More Holdenisms

Holden's newest word is cool. When I say anything to him like handsome, funny, dirty, nasty, he always says, "no mom its cool".
This morning Holden was talking to Wilson. I heard him say, "Wilson it's Flemish". I listened a little bit more, and he said it again. I asked what him Flemish was and he said "it is a language mom". I then asked him how he knew that, and he said, "because I am clever". I can't figure out where he has even heard the word Flemish before. I did ask him who spoke Flemish, and he said "grandpa" which is right, of course....
