You can think of a funeral as theatre. The star of the show is the person in the coffin.
Woe betide anyone who upstages them.
People delivering a tribute can easily fall into the trap of talking about the dead person as someone who orbited their own life.
“This is how I felt about her; this is what she meant to me, did to me, said to me; I remember that time when I…”
Too much I, too much all-about-me.
Audiences don’t like that. At all.
A funeral is for the dead person and it is for those who mourn.
But it is about the dead person and the dead person only.
Minor characters are allowed, of course, but in peripheral roles only.
