Ooooooh, they do have their routines, don’t they? Ours get to go back outside once it’s daylight and Hubby is awake to let them out. During the summer, it’s usually light when I go to bed so I let them out then.
Your MIL is lucky she’s been able to do as much as she’s been able this long. Hubby’s aunt is almost 99 now but we had to stop her from driving or cooking and such loooooong before that for her own safety. It’s hard to see them lose independence but it happens to all of us at some point.
100???
