Explanation:
¿Cómo estás? is how you ask 'How are you?' in Spanish when greeting someone your age. The use of formal or informal greetings depends on the context and relationship between individuals.
In some languages, distinct forms of 'you' are used based on social status or familiarity, as seen in Spanish with 'tu' for familiar and 'Usted' for formal contexts.
