DH died last year.
I have a wide circle of friends through a hobby/interest. Lots of people who are often at the same events, but I don't really "know" iyswim.
One of them sent me a video of him and his dog today. Just out of the blue because they'd had a nice walk. I last spoke to him briefly at an event about 4 weeks ago, not about dogs.
I'm not even a dog person 
There are other men I've suddenly started hearing from much more than I used to as well.
