I just went through an article on my computer telling me of our languages, the oldest, and such. I am so, so interested in all the languages of the world and though I can only really talk ENGLISH, I find everything written about languages so, so interesting. I am 88 years old and no doubt by tomorrow I will remember very, very little of what I have read. BUT it will always fascinate me forever.
