If this is the case then her eyesight has deteriorated quite a bit in the past few weeks.
However- living as she does in an eternal present- I don't believe she realises there's been a change.
We're taking her this afternoon to the eye clinic at Maidstone hospital. Perhaps they can clarify matters. The treatment they're giving her is supposed to halt macular degeneration. I doubt that it's working. I fear it may even be making things worse.
Another thing: she used to be picky about the TV she watched. Now she's happy to spend the afternoon watching- or dozing through- quiz shows.
But sometimes she surprises us. Yesterday she asked us about the pronunciation of the word "sloth" because she reckoned the presenter had mispronounced in a programme she'd watched the day before.
