I do not post on Facebook but occasionally receive messages from relatives. We see BiL and his wife two or three times a year, we are not really on the same wavelength.. My SiL has always sent crappy stuff out about friendship, and the wonderfulness of being a granny, which I ignore. These seem to be sent to her her group of contacts. Now she is sending out quite racist stuff so I have blocked her. I don’t want to cause a family row.
