From 2006-9 I worked as a part-time tour guide in a NYC children's "farm" visited by 3500-4500 visitors average a day during each season, mostly public school kids. One teacher apologized to me because the kids were "asking so many questions." I had to remind her it was my job to answer them...

(Ask me exactly why I know how bad education is in public schools these days, and which teachers are worst to minority kids.)
