In Trek V, when the big three took shore leave together. Kirk explained that it was because "Other people have families Bones, not us." That's all well and good, and very believable, but what was Sulu and Chekov's excuse for spending shore leave together?
Now I know the real world excuse was just for some comedy, but are we lead to believe that Sulu and Chekov really have no lives outside of their ship that they can't manage to spend shore leave with at least someone else? It was established in Generations that Sulu found time for a family, it would have been neat if we saw him spending some time with that family, instead we see him going on a nature walk with Chekov.
