>>7430108You can actually talk with an unneducated woman about complicated stuff, you just need to simplify and make it engaging, slowly building up her knowledge on the theme to the point where she understands even if you talk without making things simple. The process of you teaching her about stuff is even more engaging than talking about it with her as well.
Unless you marry with someone from your field, you will always find things that you enjoy that she doesn't understand. So, it is good to nurture that pleasure of teaching.
