Fantasy idea:

Goblins do not have a concept of personal property or privacy. They're often labelled simply as thieves, but they genuinely do not understand why a group of travellers would be upset by waking up to someone rummaging through their camp to see what they'll find, pocketing whatever looks cool, and eating their rations. A goblin feels perfectly fine walking into another goblin's house to do so.

They will also tell you everything about themselves to introduce themselves. Not only their name and where they live, but also what they do for a living, how many spouses and children they have, their parents and siblings' names, what they have done with their lives and who their best friends are. A particularly accomplished goblin can and will take 20-30 minutes to fully introduce themselves.

Travellers who manage to start a polite conversation with a goblin instead of immediately resorting to violence to defend their property will soon - to their great confusion - be invited to the goblin's home to meet their family and be welcome to stay as long as they need. This might feel strange to them, but deep down it's a cultural misunderstanding.

The goblin list of things to include in one's long introductions isn't a standardised list, but goblins have a general idea of what they expect to hear in them. They don't have a concept of private information any more than they have genuinely private property, and if someone's list doesn't involve spouses and children, that can only mean that they don't have any. If a goblin won't say where they live, that means they don't have a home. If they don't list who their friends are, that can only mean they don't have any friends.

If a traveller only introduces themselves with their name, perhaps profession, and "this is my stuff", then naturally that must be all that they have in the world. If they had friends, family, or anything else in life, obviously they would have said so. How horrible that someone doesn't have anything but a name. And if you won't tell them your name they'll assume you don't have one of those, either.
