1. Old couples
    Because it's cute
  2. A parent and child
    For safety
  3. Any other relative or caretaker and child
    Also for safety
  4. children
    Maybe for safety but also for cuteness
  5. NOT 2 or more able bodied adults!
    I don't care what relationship you have to one another, you are slowing me down and making me late to work. I understand you like each other. Hold hands later! The sidewalks were not made wide enough
