That's when Carey saw something that she'll never forget.
"When I got there and looked down, Tillie saw me but didn't come running up," Carey said. "She just stayed near the edge of this cistern, pressed with her head as close as she could get. Had she run up, we might have never realized that Phoebe was down there. She just stayed put, making it so clear that I had to come to her so I would see her friend."
Sure enough, there was Phoebe, exhausted after her long ordeal.
"When I saw what was happening, tears were immediate. It was just so touching," she added.
