Laughing, Being a kind listener, Being Sarcastic/funny, Going for walks, Art, Astronomy, Cosmology, Psychology, Science Fiction, Reading, Quality Film/TV especially with someone I care about, Gaming (of all sorts tabletop/video etc) , going for walks, Rational Thought, Religious studies, history, fresh air, discussions about the big things in life/the universe, may different types of music... this list could go on forever.
Friendly people and cuddling probably more important than any of this bullshit. =)
Cheered me up to see more activity on dgn. Woke up feeling fine then started feeling kind of depressed. I'm good now. Not just because of the DGN stuff.
