I can remember one memorial about a decade back. The talk was given by an ultra quirky odd ball eccentric elder who used some REALLY offensive illustrations in the talk (note, he NEVER got assigned a memorial talk again after that)
A well educated and well known local accountant who happened to be a client of mine came along. (Not sure who invited him)
I saw his face throughout that talk. He was stunned. I listened to everything from his perspective...and I saw why he was shocked.
Afterwards, we talked briefly, and he couldn't get out quickly enough!
He never came again.
