Bless you for caring enough to intervene in what was likely a life threatening situation Mike. And listening to your instincts. We need more people in the world like that.
It takes so little effort to just check on a person who is vulnerable.
It doesn't help when they won't help themselves, but still. . .
After some bad falls, my Aunt Betty finally agreed at age 96 that living alone wasn't such a good idea. So with the herculean effort of two friends from Texas, my two nieces and a nephew-in-law and Hombre and myself, a year ago March we managed to get her house ready to sell, got her moved into a lovely independent living facility, held an estate sale for the rest of her stuff and got the house sold.
I still check on her frequently and drive her most places she needs to go, but it is such a huge weight off me to know that if she hasn't opened her door by 10 a.m. in the morning, someone on staff will check on her. But then she is precious family.
You are more noble taking care of somebody not related to you or even a special friend. And stressful that you are in the position of caring enough to feel responsible. Blessings upon you!
