<human>: Could you distill the essence of the text into 1-3 sentences?

I left my home state for college (Midwest to California), but most of my best friends stayed and went to college in our hometown. During college, I would see them all several times a year (summer, winter, Thanksgiving, spring break) and I still love talking to them and hanging out when I'm in town.

Now that I'm out of college and living in California, I don't come home more than once a year. They all still in the same city and they get to hang out and stay close. I tried to start a facebook thread to talk and keep updated on everybody, but because they all see each other regularly, it's not really useful for them and half the time it's just inside jokes that I'm not part of.

I'm worried that I will lose my friends, and I was hoping someone would have tips for keeping up long distance friendships!
<bot>: All of my high school friends live close to each and hang out, but I live several states away. How do I stay close to them when I can't be there?
