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. =)
I love history:) Although I can't claim to be a history buff, I don't know a lot of the details. My husband knows a lot about history because his Dad knew everything that ever happened. He was a history buff:)
