Why don't you Mark, take a nice meal round to Nanny Di's and make her a cup of tea & just sit & spend time with her.
The poor woman has done nothing throughout lockdown but drag herself to your house; not always met with the nicest reception and she tries hard, SO hard to keep you happy. She will go anywhere you want her to; do anything you want her to do, just to spend time with you, just to have some company.
Before you were allowed to bubble you made an effort to meet up with her, just you two. You, personally, need to rewatch those videos and see the difference in yourselves. Both of you were happier, and enjoying each others company. You were far more caring towards her too.
