Kristin-

This was an interesting post and made me think of my friends in the categories you outlined, which was a useful exercise! Having moved across the country almost 3 years ago from PA to OR, it has definitely taken a toll on our friendships.

I feel fortunate to have a Category 1 friend here in my sister, but I miss my 2 closest Category 1's from PA. We also have 4 couples that are category 2 friends now, so I think we're doing pretty well. We don't have many category 4 friends, which is fine because that's the least useful group for me. 

I am a very social person, but not one who instinctively gathers a large group around me. I have had to make an effort to reach out since moving here and it has been worthwhile! In fact, I may be slowly turning into a friend gatherer...someone who pulls people in and mixes different groups. I've always aspired to that!
