We used to not watch any tv or videos, so I've got a lot of experience there! We do watch a little tv & videos together now. Since it is not every day & not for hours at a time, it is a nice time of togetherness for us, not just zoning out. We often end up talking about the show or quoting it to each other and cracking up.
Otherwise, we both like to play board games, so we have several of those. A few that we really enjoy are Man Bites Dog, Dicecapades (better w/ more than 2, tho), In a Pickle, Stratego, Othello, and VisualEyes. We also like this epic board game called HeroScape. We used to play it a lot more often, but b/c you have to assemble the board every time (or leave it up), we barely ever play it anymore
Sad, too, b/c once we get into it, we could play it for hours and hours. We also v often do our separate hobbies, but usually in the same room. Dh plays a miniature war game called WarHammer & it involves miniature figures that you have to assemble and paint to play w/ them. His painting table is in the computer room. The room is big, we have the comp & a couch, too. I can either play online or sit on the couch or birthing ball & do some knitting or reading to myself. Dh usually listens to a book on tape while painting. I have ZERO interest in reading his books out loud, they are not interesting to me AT ALL. His alone time is really at a premium, so I try and make sure that he has this time to pursue his own interests. Since we are in the same room, it is v easy for us to talk to each other even though we are engaged in different activities. Together but separate, kwim? Dinner time is our big family together time, so after that we do not usually have a problem separating. Sometimes dh does karate practice in the basement & I work in my sewing room.
