Does your family know you write fanfics? Do your friends know?

My parents know I write a lot and kind of support it since it helped improve my English but have never read it.
My friends know i read a lot (= every time I don't talk to them im probably too focused on a story) and once my friend read this drabble of mine that I wrote down but she traumatized herself (or she says) so she isn't touching them anytime soon
