Back to Mr T's on an autumnal Monday afternoon, his list of favourite four essential items now a familiar one. However, just before leaving his flat with his list, cash and bag, he handed me his mobile and asked if I could top it up at Tesco, and a letter that he needed posting . All in a day's work - although I did need a bit of guidance from the friendly lady at the counter who showed me how to activate the phone top up...another school day courtesy of GoodGym.
