I am sorry for your loss. I admire your doing the right thing by your friend as well.
Two years ago, my grandmother died, and my mother (who is a nominal JW) was in charge of the arrangements. One of the JW's I knew 20+ years ago came to the wake, but did not acknowledge me in any way.
Later, when I was among family members, my mom mentioned the consideration of this person in coming to the wake. I said that the "sister" really looked great (one of those people who really do improve with age) but that "her heart was so full of Jesus that she couldn't speak to me." My niece (not a JW) laughed. My mom said nothing; in fact, she looked a bit sheepish.
I am honored to be so dishonored by them. So should you be.
With love and sympathy,
Mum
