Definitely, my granny is 91. I am the only female relative in the area, so I catch it more than most. My mother is out of state & calling for me to buy an air conditioner & take it to my granny's. I dont mind, but the last air conditioner we installed, she called a man to remove from her home. She has moved to a trailer & the temps are really unbearable. There are 18 (really 18) fans in various positions in the trailer & being there w/them running is deafening. I talked to her about the ac & she was adament, no air conditioner. We have a lady who cooks & cleans for her, & I'm afraid she will find better employment, because of the heat. My mother keeps calling, but I'm between a rock (my mom) & a hard place (my granny). She doesn't want to give up as queen bee of her home, (I get that) but there are other people involved now. (she doesn't get that). w/the current situation, I can make 66% of everyone happy, me, my mom & my granny. I'm going w/the get the air conditioner, moms happy, I'm happy, she's not calling me 4 times a day, & granny's unhappy. Granny can choose to not use it, but it will be ready to use.
Enough gripping about me, you are happy, Sam will be happy, & your mom being resillent (she is 95) will find a way to be happy. You have my 66%. You did a good thing, it will work out.
