Smooth sailing

You're not entirely comfortable around each other right now, but that's not necessarily a bad thing. Friendships need to change and stretch and grow. Perhaps one of you is a little itchy in their own skin, doing some necessary evolving and requiring a little space in which to do it; maybe you're each exploring new acquaintances or interests, stuff you want to keep mostly for yourself for a little while. Keep your lines of communication open -- they may not be crackling now, but they will be again.
