This morning, as I sat down to browse the Interweb, I took my specs off - not needed for the computer - and they fell apart.
It looked as if the metal prongs holding the soft bit that goes over my nose had snapped away from the frame. I found my spare pair and wore them all day, thinking I would have to go and buy some new frames - an expense I wasn't planning on this month.
Then just now, when I'd hunted about and found my last prescription, I had another look at the broken specs, through the lenses of the spare pair, and spotted that there were tiny screws in the soft-bit-that-goes-over-my nose. The screws had simply come unscrewed! Half a minute with a tiny screwdriver, and I've just saved myself a few hundred pounds! I think I'll go and order some Shetland tops instead.
