Bread starters are like Tamagotchis, with all of the feeding and caring and keeping them alive. Do you remember Tamagotchis? They were these little electronic key chains that became popular in the mid-90s. When you got your Tamagotchi, you would pull a little plastic tab, an egg would hatch on the screen and a little creature was born, which you then had to take care of. It was a toy, kind of.
They became popular when I was in the 6th grade. Our entire class was constantly running to their lockers or sneaking glances at their Tamagotchi under their desks to feed it, clean up their electronic "business" and play a game where you had to guess which way it would turn its head (and that's what we called a game back when I was a kid). I remember one of my classmates had five or six of them all on one key chain; sextuplets, if you will. The minute he was done giving medicine to one Tamagotchi another one was ready for bed while a third was crying because it wanted to "play" the game. They finally got so disruptive that a teacher confiscated them and locked them in her desk, which seemed so cruel to us. We imagined them in her drawer, sitting in their own filth, slowly withering away until they died (I'm pretty sure the only thing that happened when they died was they got little electronic X's over their eyes and you just had to hatch a new one, but it seemed devastating).
