Weird! Yesterday I got a post (not a PM) on my FB page from one of my SiLs asking me to ask Kev to phone his brother (her husband).
Not sure why she didn't contact Kev directly, but he saw the message on my page before I did!
Turns out that one of Kev's BiLs died yesterday.
Today I looked at the FB pages of the deceased's wife (i.e.Kev's sister) and daughter

Nothing.
Plenty of new posts today and yesterday, but nothing at all about husband or father dying.
I can understand a reluctance to post about it so soon, but I don't understand all the happy posts and memes that they have posted.
