I'm an 84 year old woman and can easily pass for much much older

Rio Grande - I'm an 84 year old woman and can easily pass for much much older. So on my weekly Rio Grande grocery trip in I was startled by a man shouting, "don't touch my son". You see, I was going down the cereal aisle when a young boy about 8? years old was standing on the metal shelve retainer trying to reach a toy. There were many empty pegboard hooks at his eye level and he had trouble trying to catch his balance. I placed my hand about 8" behind his back and told him, "I will get it for you". I wonder if the father was a lawyer and would sue for negligence when his child got hurt. WATCH YOUR KIDS!
