And just how am I still alive?

My 7 year old son was recently hurt in a horrible parental judgement move. We had the TV on top of the dresser and foolishly believed 1. it would never fall over and 2. he wouldn't be so adventurous to climb on said dresser. Luckily, by the grace of God, he walked away with minimal injuries. But me? I still hear him screaming of extreme pain in my dreams. The fear in my husbands eyes as he forced his way into the room to find his son trapped. And the looks of people when I say what happened. Then one day as a women stopped mid sentence and said "Why is he wearing that?" that being a sling to keep his hair lined fractured arm from moving I realized I had had enough. Seriously people. He is not the first child to get hurt in this manner. Although I may be the first to be so open about it because I NEVER want that to happen to anyone else. Then it hit me. How in the Hell am I still alive for this to have even happened? I've graced this Earth for over 3 decades and survived all that you say will kill my child today. I rode in a car with no seat belt...sometimes on my Dads lap as he drove. Wore no helmet riding my bike and have memories of eating gravel in the Church parking lot due to seeing who could create the longest skid mark. I jumped on my bed and bumped my head just like the monkeys you warned me about. My parents snapped pictures as I held a beer can in my barely walking hands. Smoking in the car while the windows were rolled up was never given a second thought. And I walked to school by myself through an alley. I played outside until the street lamps came on or Dads whistle was heard a mile away. We camped, and I walked barefoot. I survived with no brain damage, permanent scares, or ringworm. Now, you lady who asked so curtly why my son is in a sling, you for sure have lived much longer than I and I'm sure your sons have endured more due to the ignorant bliss we parents sometimes have. I have learned from my mistake, I assure you no TVs are no longer on dressers, and one day my boys will be sharing stories of survival from the willy nilly ways of live "in their day" too.
