Hello all, today I signed up to this after seeing it on someone's Instagram. I have one surviving grandparent who I'm checking up on as best I can, but I also have some spare time at the moment and thought it's a nice idea to help combat loneliness in elderly people. You get in touch with your matched "grandparent" via phone/video call, or by sending letters. There's no pressure to take part, but I thought some of you may also be interested 
The website is

I hope you're all well at this time. Feel free to post other initiatives if you think others will be interested.
