i am actually impressed that you know another language. English-speaking people seldom can. At least the ones I have meet. But why bother when the whole world tries to learn your language?:)
I must admit that the Welsh bits I have found on the internet. I do try to check with different sites on the Welsh Gaelic language, but the swear-words of Gwendolin is not the hardest to translate, especially not when the nice Welshmen create whole internet-pages with swearwords.
