If the answer is less than 371 days, you're doing better than average. Another tidbit from Dana Liebelson's Facebook research rundown at Mother Jones:
Facebook also noted that "what parents say when they're not talking to their children is just as revealing; they use higher levels of ideology (agree but, obama, our government, policies, people need to, ethics), swearing and slang (ctfu, lmao, fucker, idk), and alcohol and sex terms (tequila, glass of wine, that ass, sexy). Ew.
"Tequila, glass of wine, that ass." Our mothers, ourselves. [Mother Jones]
