I didn't do today's crossword, so I didn't catch any germs. In one of the crosswords I did over the past few days, I had a cricket clue, a clue involving a cricketing term - I got the answer, but deleted it from my brain immediately. I like to keep space clear for more necessary matters.
Your mobile sounds delightful, though it's a pity you can look at it only when you're at home. My mobile, with photos of butterflies and robins and lots of holiday pics and bus timetables and train timetables and book reviews... goes everywhere with me. I know you'll be astounded, but it weighs only an ounce or two.
I can sympathise with your nephew re his memory being full. That happened to me occasionally, but I discovered I could send things off to the cloud - a super-duper storage area. (You won't find it on the High Street, by the way, don't go looking.)
