Thanks for your very supportive comments.
Switched on mobile phone earlier to find two messages from her already, sent at 0818 today! Charging it is a great reason for not replying. When I finally agree to her coming round again, there will be a comment about me not answering immediately and possibly that I wasn't telling the truth. Did this before, so took her into kitchen to prove washing machine was actually on!
Already wary due to her comments about my not knowing what the neighbours are up to. I'm not one for constantly going in and out of people's houses, especially when they need space due to illness.
She's taking up valuable time, that I should be using for myself, so do need to limit her neediness.
