Have You Ever Suddenly Lost All Interest in an Anticipated Title for No Good Reason?

I know that feeling, but in another context. I don't know the correct term, but I am pretty sure it is that one feeling young children have when they fight over a toy, but once they have it, they don't play with it.

I don't mean this in bad faith. I am certain there is a reason for this.

In my experience, kids do that because of sibling rivalry. But I don’t think that’s the term you’re looking for. Perhaps a better example is a crush on a girl who isn’t available, but then when she is available, you’ve moved your crush on to someone else. The term is “impulsiveness” - that is, you want something, but lose interest in it once the mystique/attraction wears off.
