How does craving (taṇhā) relate to neutral feelings?

How does craving (taṇhā) manifest with respect to neutral feelings? In Dependent Origination (or dependent co-arising, however you'd like to call it), it is said that Craving (taṇhā) follows on the heels of Feeling (vedanā). Feeling, in general, is of 3 main types: pleasant, unpleasant, neutral. I do see how craving/aversion manifests with respect to both pleasant and unpleasant feeling. But how does it relate to neutral feeling? How is it that I either lust after or try to avoid something that is truly neutral?
