I find the idea of not having a funeral odd, and would never have not had funerals for my parents. For both of them my children talked about their grandparents with love and humour. They really were able to capture their grandparents exactly. It’s part of the grieving process, and although we had a wake, with food (people who had travelled needed to be fed) we most certainly did not have a party, just a pleasant coming together of family and close friends over food and a drink.
I will not leave any instructions regarding myself because a funeral is for the living, not the dead. It’s an opportunity to acknowledge the grief, and to remember the person, and to draw comfort from being with the people who also cared for the person who has died.
