I want to point out how you evolved in a week's time. The breastfeeding mom is very much dependent on her suckling infant and is left to wonder why her baby is not cooperating; I see the crops and the rain as two separate entities, and while there is a dependent relationship( well at least as far as the crops needing the rain), the crops really have no influence over and cannot claim any responsibility for the rain's behavior. The problem is that the rain really doesn't need the crops, so it's back to the analogy drawing board for you. Besides, I really don't like thinking of myself as a plant...way too passive.
