i find it best not to talk about Buddhism with non Buddhist unless they ask specific questions. I'll talk about work with out gossiping about other co-workers, I'll talk about what i did over the weekend etc, but i try to avoid anything "deep", people know I'm a Buddhist at work, i have no idea how, it just got around somehow, so i don't have to say anything about it or explain why i don't do certain things. i don't talk about it with family unless i have to explain why i wont do certain things or am against certain things or why I'm doing things they don't understand. all my friend for the most part either are Buddhists , have converted to Buddhism after hanging around me, or are into weird stuff that they think is somehow the same as Buddhism, so i have no problems talking to them however.
