Rain, rain, go away

I have a book on nursery rhymes, which i introduced to deardear ONCE a couple of weeks back.

Out of the many nursery rhymes in the book, the one that captured deardear's attention was

Rain, rain go away.
Come again another day,
Little Jenny wants to play.
Rain, rain go to Spain,
Never show your face again.

I only introduced it ONCE to her n yesterday nite, to my surprise, she found the book in one of her toy bins, brought it to me, FLIPPED it to the page of the above nursery rhyme, and said "Rain, rain..."

She remembered!!
