Explanation
In Spain, pointing with the index finger is generally considered impolite or aggressive in everyday social interactions, especially when directed at a person. Spaniards often prefer to gesture with an open hand or nod their head to indicate direction or a person. This is rooted in a cultural emphasis on personal space and indirect communication.
Local Tip
Instead of pointing, gesture with your whole hand (palm up or open) or use a slight head tilt to indicate a person or direction.
