Accidents will happen, as Elvis Costello astutely pointed out. Furthermore they often occur in the most innocuous of fashions, as I shall now tell. Myself and Mrs P were over our local park today with our two and a half year old grandson Oscar. It is located directly behind our home and has a small children’s play area as well as various adult exercise equipment. One of these items is a low, wooden ramp whose highest end is no more than eighteen inches off the ground. Oscar likes to climb on this, run to the end and jump. Naturally, he did this today when we visited. Mrs P then followed suit (at his request) and stepped off onto the soft, child safe surface. Her right knee gave way and she fell over. Despite the short distance and the soft surface, the fall was sufficient to injure her knee, as there was an audible crack. She subsequently could get up on her own and I had to assist her so she could sit on the aforementioned ramp.
