Yes, generally you can hug a girl in public, but consider the context and cultural norms.
Based on the reference, a simple hug, perhaps even a kiss on the forehead, is generally acceptable in public. The reference states: "Hugging and a kiss on forehead is no problem at all".
However, the reference suggests that more intimate displays of affection should be reserved for private settings: "Well if you go further, you should find better place than a public area to do that."
Here's a breakdown of considerations:
- Relationship: A friendly hug between acquaintances is perceived differently than an intimate embrace between romantic partners.
- Culture: Some cultures are more conservative regarding public displays of affection than others.
- Context: A celebratory hug after an achievement is viewed differently than a lingering embrace in a crowded street.
- Consent: Ensuring that the girl is comfortable with the hug is essential.
In summary, while a casual hug is usually fine, be mindful of social cues, cultural sensitivities, and the level of intimacy involved. Anything beyond a brief hug is best reserved for a more private setting to avoid making others uncomfortable or being perceived as inappropriate.
