How do you see to find your glasses without your glasses on to see?

I grew up listening to a tape recording of "What's the Matter Nannybird?" by Peter & Hanneke Jacobsoff. It was cassette tape recorded for me by my Tia, Pat. I can still picture the handwritten title in red ink directly placed onto the label of the tape. In short, it is a Christian Children's story about the way God reveals Himself in mysterious ways. Nannybird, literally a bird, loses her glasses and goes through the entire story looking for them with help from friends. From time to time I recite to myself as Nannybird did, "How do you find your glasses without your glasses on to see?" It amazes me, that after all of these years (roughly 20 yrs), I can still hear Nannybird squawk something about trying to find her glasses. The line makes tons of sense to me since I am not only near-sighted, but have astigmatism and wear glasses. My world is a blur without these babies. I constantly have to repeat to others that what ever it is they urgently need me to see, needs to wait until I find my glasses. If by some bizarre reason (eh hem... like wearing contacts) I've misplaced my glasses, then I have a tremendously difficult time finding something I can't see. I fondly recall the story and have searched for it in my stash of old cassette tapes. Needless to say, I haven't been able to locate it. I think my son would enjoy listening to the story over one of our road trips. If anyone knows where I can find a copy, drop me a line! ;o)
