My aunt and I were also thinking about our own imminent deaths and what each of us wish for our funerals. You may think that discussing, planning or wondering about one's non-life is creepy, odd, or strange but what do you want people to do in honour of your life and death? All a part of a will and living will in the 21st century. Here are my thoughts with the flowers.
My choice would be to have a memorial service sitting around the stream right below Arta's cabin at Shuswap Lake. No one in suits, dresses, or skirts, attend in casual attire. No one presiding or being in charge other than my immediate family members. If they wish, they can find a friend who may want to be the MC. I like MC's (only the ones who leave out the lame, tacky jokes).
