Who contacted Angela?

As we were driving, we finally came to our destination. Seeing it, I nodded, and with help, I came out. Looking around, I kept jumping inside and saw the doctor there, he said, "Knee."

"Yes, last time this year," I said. Hearing me he smiled, and we came into the room. While being here he said, "What were you doing?"

"Going after my son on my knees," I said. Hearing me he nodded, and when he was done all there I took painkillers, and while I could move finally I could smile, and seeing his look at me I added "All is great now."

"I hope so. Try not to do this anymore" he said.

"He kept trying to walk so as to not have pain in my back I went on my knees" I said, trying to make excuses. Looking at me he shook his head. When I nodded, and not long after I came out. Looking around I came back to the car, and while sitting in the back I said, "We can go home."
