My dads got FIVE pairs of glasses at the moment, all in various states of disrepair. He wears them indiscriminately, even though at least two are for different things. He sometimes put two or more pairs on at once which looks very funny. I'm not really sure what situations he considers wearing them, but I know that he uses none of them to read because he uses a magnifying glass! He spends quite alot of time faffing around sorting different "combinations" of pairs to wear, losing then, finding them, losing them again, and then says "I dont actually need glasses you know!" Ive got a feeling its not the AD....Ive got a feeling it's just dad!
