That is true.
After witnessing so many begging Go Fund Me links for funerals, I recently wondered if funerals were actually necessary at all?
I have never been an extrovert so do not need anyone to get together and remember me. They can do that by themselves. But people do like to share stories and memories of departed ones and funerals (or wakes anyhow) allow that coming together part. As was said, funerals are for the living so it is not really up to the ones who go.
My dad asked if he could have his body donated to a medical school, so we can skip all the nonsense.
He is still here, but I have heard bad things from medical students who are learning anatomy and how disrespectful many can be to the cadavers. I am honestly not sure about that.
