I remember when the "15 minute" option was put into effect. For someone like my aging Mother with multiple health problems, it truly has been a "loving provision". (I can't believe I just typed that.)
What's unloving is the whole hour-reporting, number-centric approach to FS and the labels (regular publisher, irregular, inactive) and guilt that go along with it. I'm pretty sure my Mom has always been able to get in at least an hour or two a month, but for her, it's comforting to know that the 15 minute option is there if she needs it.
The only way she will ever miss a month of FS is if she's in a coma. At this stage of her life, it's an integral part of who she is.
