Ok.
So the barn owner lives offsite and has to commute to her own barn while also caretaking an aged father and possibly holding down a job?
And the barn used to be better because there was a trainer who was doing a lot of work, either in exchange for rent or as unpaid labor, until she got her own property?
Now she is building a suite on site for the elderly father and is she moving back onto the property?
Father could still be ill or have a chronic or fatal or degenerative disease even if you see him mobile from time to time. When older people start to decline they rarely fully bounce back.
My interpretation of these details is that barn owner was never the caretaker of the place in its “good” days and doesn’t have the skills, bandwidth, energy or cash to either do these jobs or hire someone else.
Does she ride or teach? If not, the condition of the rings may not matter to her. While trainer needed rings to earn her income.
