Question: Consider this quote from Mark Twain: "Familiarity breeds contempt - and children." Does it mean having children is a bad thing? Could you explain what the children imply here? 
Answer: I think you are confused because you see familiarity as containing the root word "family"."Word Choice: Familiar vs. Familial" It explains that "Familiar" means "Known from Experience", whereas "Familial" is "Relating to Family", as mother, father, brother, sister, cousins, aunt, uncle, etc. "Familiarity breeds contempt" applies to the circumstance that becoming too emotionally close (familiar) to someone can breed bad feelings for each other. As for the Mark Twain quote, "Familiarity breeds contempt - and children." is a play on words, a joke; treating "familiarity", as if it was referring to family, and the word 'breed' as 'breeding children', rather than feelings. It could be seen as a friendly dig on children, or it could be seen as just a funny play on words.

Question: In the movie Easy A, the character Todd said "See you at salt mines" to Olive when they met at Melody's party. What does salt mines mean? Does it really mean "a mine for salt"? 
Answer: Salt mines are, of course, just mines for salt, but in classical times, they were staffed by slaves, typically POWs, and the work was so arduous and the environment so dangerous, that being sent to the salt mines was considered a death sentence. To describe any job as a "salt mine" is a hyperbolic way of saying the work is unpleasant, arduous, or repetitive. edit reading John's reference, I realized I was confusing salt mines with classical tin mines (also very unpleasant). Salt mines are more recent and their staff, not necessarily POWs.
