Study! Even out of school I still browse the peer reviewed, double blind studies on topics I'm interested in (Biology, medicine, ect). But whenever anyone asks what I did over the weekend I say netflix because they get that. X-D
Fanfiction. I read more fanfiction than published fiction at this point, and while my husband is aware, he helps me keep that particular secret from the rest of the people I know in meatspace.
I don't have time for it much--- but I do like playing video games. It brings me back to the nostalgic days of my childhood not having to worry about adult-ing. I just beat a really hard game last month and got so excited I was worried my neighbors might have heard me yelling. It felt like a huge accomplishment.
I also like to go to parks- nature is my jam. I love it so much. There's a park with big creeks about 20 minutes from us, and I can walk along the bank taking it all in.
