Parents holding onto leashes attached to children in full upper body harness restraints SCREAM "I have no freaking clue how to raise a human! Please get me help before this child-thing turns 5 and I unleash it into the general population and start sleeping with my door locked!!! I'm an idiot and should've never birthed/adopted/opened that basket left on my doorstep! I'm sorry society; slap me silly and enroll me in a parenting class the next time you see me and my kid-on-a-leash at the mall or anywhere in public!"
