What a wonderful language English is. . .
This reminds me of a lecture on how difficult English actually is, with all its inconsistencies and exceptions, and how incredibly smart small children are to be able to actually learn it as fast as they do. I made up a little story for the kids:
The father mouse said to the mother mouse and his three little children mice: "Our house is too small so we need to get a bigger house." The three little mice called out together: "But why don't we get and extra little house so we will have two hice instead of, on so we can stay in the little house and you two in the other house?"
Then the Mother mouse said: "But, children, if we get en extra house then we don't have two hice but two houses. Remember this, it's important to use correct English when you speak, . . .the plural of house is houses! OK?
"OK", the three mice called back: "Whatever, we heard you, as long as we have two houses it's fine with us".
