Do we want the focus to be on the bad things, which we all have, do we want them to remember only the good things, or is this the time for balance? The dictionary defines eulogy as a speech or piece of writing that praises someone or something very highly, especially a tribute to someone who has recently died.
The totality of our life will be judged by someone else, not the people who hear or speak the eulogy. I only hope that when I die, people remember that I helped people more than they remember the people I hurt. I hope they say that I was a good mother, not an absent mother. I hope they say that she taught many children how to learn not that she failed some. I hope they say she was a pleasant, friendly person, not a vixen. I hope they remember that, in spite of all of my failings, I did my best.
