Okay, the user wants me to translate "hob-nob" into Vietnamese. Let me check what "hob-nob" means. It's a term that refers to a person who is involved in social or political activities, often with a connotation of being a busybody or someone who meddles in others' affairs. Now, I need to find the appropriate Vietnamese equivalent.
Looking up possible translations, "hob-nob" isn't a common English word, but it's similar to "busybody" or "meddler." In Vietnamese, "người tò mò" means curious person, but that's not quite right. "Người thích xen vào chuyện người khác" translates to someone who likes to meddle in others' business, which seems closer. Alternatively, "người thích can thiệp" could work too.
Wait, maybe "hob-nob" here is used in a specific context. Let me confirm. The user provided the translation rules: if the content is already in Vietnamese, leave it as is. Since "hob-nob" is English, I need to translate it. The best fit would be "người thích can thiệp" or "người thích xen vào chuyện người khác." But I should check if there's a more standard term.
Alternatively, maybe "hob-nob" is a proper noun or a specific term. If it's a name or a specific term, it might not translate directly. However, given the context, the user probably wants the meaning translated. So I'll go with "người thích can thiệp" as the translation.
