A big part of growing up involves making mistakes and learning the consequences for making them. After all, our parents could tell us not to do something all day, but it was hard to listen when we had no frame of reference for what could happen if we did.
Most of the time, our big mistakes usually either led to something breaking in the house or led to us hurting ourselves.
Unfortunately, one child's actions have resulted in far more serious consequences than he was likely prepared for.
