Don't forget in the 80's a parent could get away with letting their kid play at an arcade or roam the stores in a mall safely. Looking back, everywhere I went with my mom I went right to the toys or arcade and she went her own way. I knew to stay put and she would come get me. I wouldnt dream of letting my kids run off in a walmart on their own.
Now, is it really that we were safer, or have we been programmed to be over protective?
