I'm not sure what specific 'thing' you are referring to. If it's something like a collection of items, it depends on what it is. For example, if it's a collection of stamps, daddy might be happy to show it if he is a stamp collector.
In most cases, if you haven't restricted access and your friends are connected to you on the relevant platform, they should be able to see your stories. But it's all about the settings you've chosen.

Sure! Daddy's collection could be really interesting. For instance, if it's a coin collection, he could tell you about where he got each coin from. Maybe some were from his travels to different countries, like the euro coin he got from a trip to France or the old shilling from a visit to the UK.
