Interesting, at my 90 year old grandma's JW funeral 3 years ago, we broke all the rules. One of my cousins (a non-jw) give an eulogy for my grandmother, even associating the year of her birth with the proclamation of Mother's Day, before the Witless dunderhead half crazed elderly elder gave his recruitment speech.
Most of us wrote a small note of a special remembrance to Grandma which was tucked in her casket for burial and each one of her remaining 4 children and 26 grandchildren threw a red rose onto her coffin before leaving the cemetary. One of her remaining children is an elder and at least three of her grandchildren's husband's are elders. No one said a word before, during or after. Oh yes, there were tons of flowers.
