Yes, I can do a crossword and watch TV too. But I hadn't really realised how much multi tasking I do until I cam out of hospital recently (the KNEE) and had to sit and tell Theseus what to do, for example cooking a simple meal, doing house work - all of which involve " doing this while that is happening but keeping an eye on..." he is not a domesticated person!
After the first week, a cleaner was brought in, and I sat in the kitchen taking him through cooking things step by step. He could honestly only cope with one thing (done very thoroughly, I have to say) at a time. Week two, I cooked, though DD brought round some lovely things too.
