I feel you, I really do. What you say has a relevance to more than just writing. We do this sort of thing because the new and shiny always seems to draw attention. The new is less complicated somehow and therefore, easier to deal with. Although it could be, it isn't necessarily so and could be just as hard, or harder, to work on/with as something older. Remember, L&G and Nemesis are old friends and deserving of attention and just as it is when you make new friends, you can't neglect the old ones and expect them to still like you when you find the time for them. Having now been neglected, it's going to take some work to get back those relationships. Believe me, they are worth it and you know it. That's why you're thinking about them, because you know they are still good friends and deserving of your attention. Now you just have to work on rebuilding the relationships and if they begin in starts and fits, that's okay. As long as you continue to work on them, you will come together eventually.
