Ok, since u tag me. Here's my sincere advice.
Firstly, if u already have intention to hide, it means u know your this hobby is quite unique and not every adult may accept. If u decide to hide it from them, next time if they find out on their own how? It will be even more awkward and "why didn't u say last time" topic will come up. Somemore u post it on social media, it's just a matter of time people may found out or maybe your daughter slip of tongue say out. Then lobang pichak. Later your daughter blame u for a relationship ruined how?
