shallow means when someone is thinking how it looks. like if u get a puppy cuz it matches a skirt u like to wear and not knowing that a puppy is alive and needs water and food to and that person would be shallow
Usually when someone is described as a 'shallow person,' it means that they lack depth. For instance, a shallow person might be more worried about what someone's car looks like than whether or not that same person is honest. Another way to define a shallow person is one who is more concerned by what's on the surface than what lies beneath the surface.
