[Q]: Question: I need a single-word to describe something good that (unexpectedly) resulted from something bad. This good thing could not have occurred without the bad event happening first, as a precursor. Example sentence: "I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was the ____," (something like that). 
Answer: silver lining "I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was the silver lining" From Wikipedia A silver lining is a metaphor for optimism in the common English-language which means a negative occurrence may have a positive aspect to it. Etymonline says: a "bright side" which proverbially accompanies even the darkest trouble; by 1843, apparently from oft-quoted lines from Milton's "Comus," where the silver lining is the light of the moon shining from behind the cloud. Was I deceived? or did a sable cloud Turn forth her silver lining on the night? I did not err, there does a sable cloud, Turn out her silver lining on the night And casts a gleam over this tufted grove. To which Thomas Warton added the commentary: "When all succour eems to be lost, Heaven unexpectedly presents the ilver lining o a able cloud to the virtuous.".

[Q]: Question: I need some information from person A. Person A is not willing to give it to me. So instead of asking directly I keep asking secondary questions hoping that he may say something that might (partially) hint me the information I need. I may even ask other people. Or keep asking so many times that person A would have had it and just told me because he can't stand my questions any more. It's like extorting, but without using threats or violence, but cunning and perseverance. What word am I looking for?
