Separating Private and Blogging Worlds

I tend not to drag family and friends into the blog, but sometimes it would feel almost dishonest to not mention that I'm visiting say, my mom, but I try to do it in passing.  Sometimes there are milestones I really want to share with readers who know my family or friends, because it affects, to an extent, what I'm thinking and feeling.  However, sometimes the person involved will say something like, "Your private and blogging lives should stay separate."  So I won't mention that someone I know got approval of an important document and now moves on to a new stage in life.  And I'm delighted and pleased and proud.
