Dear Yoda, my sincere condolences on the passing of your grandmother. I hope good memories of her will be of comfort.
I gather from your description of the funeral that you were at least somewhat emotionally prepared for . . . oddities. May any trauma associated with the event soon dissipate.
Thank you for sharing your experience.
