Talk to her and spark memories of the true Mass (if she's old enough to remember). Perhaps, God willing, she will request her funeral Mass be the TLM. Or, even ask her if she will consider it.
prayers for her
Thanks everyone for your input. I will ask my SSPX priest about it.
Charles, thank you for your prayers. Your idea is a good one, but the problem is her condition has deteriorated to the point where she barely talks; and when she does talk her communication is hardly intelligible, although not completely. She is in an assisted living home. Also, having a relatively extended conversation with her is not possible anymore because she soon seems to "tune out" after conversation has started.
I will still bring up the TLM to her, but there are some family members (aunt, uncles, brother and mom) that are somewhat manipulative, therefore even if she wanted to have her funeral at a TLM, I fear some family members would not allow it. These same family members insisted on my grandma going to an assisted living home over 2 years ago, despite efforts by my sister and I to have her move in with my sister (in a different state). We felt this would be more healthy for her as she would have constant love and support from my sister and her family; and my grandmother could still feel as if she has a meaningful role in helping with her great grandchildren. This sense of purpose would have been good for her mentally, too. Whenever an elderly person loses purpose, significance and/or stimulation such as tasks, they tend to decline very rapidly which is exacerbated by a sense of loneliness. This is exactly what happened to my grandmother as soon as she went into an assisted living home. Those places are a joke and a complete guarantee to a speedy decline for the resident/patient. She has physically deteriorated to the point of being confined to a chair, too.
I did have my mom bring her one of my Brown Scapulars (which was imposed by a priest on me), but when I went to visit her I discovered it taped to her bed's head panel. This was frustrating for me to see; and I asked my mom why she was not wearing it. I told her she is supposed to wear it, but my mom said the reason it's not around my grandmother's neck is for her safety - so it doesn't get tangled around her neck or strangle her. So I just left it alone, but I'm glad you brought up the Brown Scapular, because I'm going to insist she wear it now.
Thanks again for your input and prayers. Jesus Christ bless you and all of us and Blessed Mary pray for us. Amen.
