I think everyone should have a funeral.
It doesn't have to be a service- religious or otherwise- nor does it have to be formal.
People just need to get together with other people who are mourning the passing of the same person.
Sorry for your loss.
I want a sendoff that looks exactly like my life. I want the family I talk to, not the family that I haven't talked to in 25 years. I want the friends that are actual friends, not the people that call when they need something from me. I want them all to be laughing and having a good time. I want stories told and I want them making fun of me and each other. I want it like I was still there...because I will be.
