Your limits are otherwise known as your boundaries, they’re what you use to protect your power, to govern it responsibly. They’re what allows you to interact healthily with others.
There are some instances where objectification is entirely appropriate and needed. For a short while–for example–a baby cannot walk, and cannot feed itself. They have no agency, no power to decide on where they go or what they do. As parents or caregivers we take on this agency. We are literally a baby’s arms and legs… we dress them, we feed them, we pick them up and put them down.
