Helping an old lady

While walking going to the school one afternoon to pick up my kids I saw an old lady sagged on the foot path leading to her house and beside her was 2 big rubbish bins. HELP with a gesture of her hand to come to her was all I heard. I hurriedly went to check and asked if she was alright. Looking so tired and pale, she didn't bother to answer me so I checked and tried to piece out what was really happened. Then, the sight of blood on the foot path right beside her frightened me. My speculation confirmed that she had a fall and knocked the left side of her head, which was partly covered with blood. It had a deep cut and quite big. I wondered for how long she had been there waiting for someone to help her. I ran across the road to the people who were in the process of building a house and asked for help to ring the ambulance because I didn't have my mobile phone with me at that moment that I needed it the most. I went back to where the old lady was and glad I saw a car moving out from the driveway of the house next to the lady's house and tried to stop the driver who hurriedly scrambled out of her car upon knowing what was happening and decided to ring the old lady's daughter right away. Then a young guy from the construction site came over and rang the ambulance. He was really nice and even asked the people in the hospital what to do while waiting for the ambulance for the lady was losing a lot of blood. Per the hospital advice, we put a damp cloth to where the cut was and applied a little pressure on it and let the lady lay down with her head on two pillows which I took from her house to make her more comfortable. I noticed that black ants started to gather around her, maybe it was because of the smell of the blood that attracted them. I stayed there until the ambulance arrived after about 15 minutes from the time the young guy rang them and the old lady's son arrived thereafter. She was admitted in the hospital as far as I know and I hope she is doing fine now. I haven't had any news about her since then.
