Calling someone "Aap" is generally a sign of respect in Hindi and Urdu. It's the polite form of "you," used when addressing elders, superiors, or anyone you want to show deference to. Therefore, if a boy calls you "Aap," it likely indicates respect.
Here's a breakdown:
- Respect: The primary meaning is respect. He is likely showing you that he views you as someone worthy of respect, perhaps due to age, position, or personal qualities.
- Formality: It could also indicate a more formal relationship. He might not know you well enough to use a more casual form of address ("tu" or "tum").
- Cultural Context: The use of "Aap" depends heavily on cultural norms. If you're significantly older than him or in a position of authority (e.g., teacher, boss), it's quite normal.
- Sarcasm (Rare): While unlikely, in some rare contexts, it could be used sarcastically. However, this would be heavily dependent on tone of voice and body language and is not the default interpretation.
In summary, receiving "Aap" is mostly a good indication of the other persons respect or formality.
