In my past relation, the girl was all about "decency" and "properness". Gaming was "improper" for a young adult. (I tried to explain her what the average age on GB [minus the KotOR and Fable boards
] was, but she was good at ignoring facts.) Not that I stopped gaming.
Lots of other things. Doing silly, funny things were off-limits.
Worst of all: sleeping with the window open, an absolut must for me, nearly got forbidden.
