My mom's cousin has bad cancer, all over her body, and just had a port put in. She started her chemo treatments recently, and her first visit, while waiting, a woman came up to her and said "Everything's going to alright, you're going to be okay."
Which was nice, one stranger comforting another, and then she looked at the woman's name tag, it said "Olga"...
Olga was her mother's name.
I believe that angels are among us, everyday , everywhere, and we only have to be open to hear them.
