I agree paddyann it is a huge comfort when friends support at a funeral. I was hugely touched by some of DDs’ friends coming to Paw’s funeral from London and further afield, not to mention friends we had not seen for over 25 years.
I was similarly hurt when somebody who has known us since university 50+ years ago, and coincidentally lives only 3 miles away, excused herself by saying she and her OH were “both tied up, doing different things that morning”.
Not sure the “friendship” can come back from that.
So listen to your heart, and go.
