most of my friends share my hobbies, such as playing D&D. other than that, my closest friends all know I write (mostly E-rated) fanfics. one of my oldest friends since childhood sometimes beta-reads my fics and we help each other out when writing some scenes. I don't know if that means they know too much about my hobbies. but I for sure know that I trust them and their opinions a lot when I ask them about my writing and how to improve it.
