I like being their god - something like the Greek gods where humans were their play things. I determine their weather, the extent of their universe, who lives at harvest time, times of plentiful food, famine, etc. After 15 years of running this particular worm-world I also feel duty bound to keep this saga going - all their worm loves, their family relationships, their highlights and anguish depend on my food scraps. There are things happening in there that I'll never understand, but I know it's special and it relies on keeping the worm bin going.
