HAVE YOU EVER FELT THIS WAY?

It suppose to be a good gathering and meet up with other friends at the Putra challenge park. I had invited a friend who is new to wall climbing. We were suppose to meet up with the rest of the gangs in the afternoon.But she wants to have breakfast together with two other friends who could not make it the last minute. So she picked me up at 8.30am and then went on to pick up another friend before we met up with our two friends to had breakfast. After breakfast we headed for putra jaya. It was around 11.30am or so, after paying the necessary fees we were ready to climb. She did ok for a first timer on the wall climbing. Then one of the friend was tired after two climb and so we switch to another area which was the bouldering wall. This part of the climb does not require safety rope. She did climb for a while then suddenly she felled down and I could not catch her in time and she landed on the mattress which we usually refer to the crash pad. It was only about 4 to 5 feet high , then I heard her saying I have broken my bones. I thought she was joking.Then I saw something swelling outward and I reliase she was telling the truth. Quickly I got the people in charge there to call the ambulance and within half an hour it arrive and she was rush to the hospital at Putra jaya. Waited for a while before her brother in law and husband came. Since it was not know when the doctor could attend to her,  I was requested by her husband to drive back her car to klang while they made arrangement to transfer her back to a private hospital in klang.  Prior to that I had apologized to her for I felt I had indirectly cause her to have this mishap. If I had not invited her then the accident would not had happened. Despite her assurance to me that it was an accident and I was not to blame myself, but somehome I still did not feel easy at all. Last night I did not even had a good sleep, as  I kept on thinking of what had happen. This afternoon I visited her at the hospital. She had been operated on the night before and now recovering. And again she told me not to feel bad about the whole incident. I had told myself maybe I should be more careful whom I invite for any future activity. Have you ever gone through such experience before or something similar?
