Three of my closest friends live in different cities (we haven't lived in the same place since college) and lately I'm finding it harder to stay connected with them. One of them I see once every year or two, the other two I see maybe twice a year. I text regularly with each of them but I sometimes feel like there's not much to say. We're like "How have you guys been?" "Good, you?" It's just hard to try and catch someone up on details when you're not part of the details. I don't want to end the friendships, any tips for long distance friends?
