Not every question "can be answered by love, fun or ice cream," says NPR's Scott Simon.
As part of StoryCorps' National Day of Listening project, Simon explains how he responds when asked, "Where did I come from?" by his 6-year-old daughter, Elise.
Simon and his wife, Caroline, adopted Elise and another daughter, 3-year-old Lena, from China. They've grown up knowing they were adopted and are naturally curious about their birth mother.
"We don't conceal any details from our daughters — they're cunning enough to catch us anyway. But every few months they absorb a little more and the older and smarter they get, the more questions they have for which we have no real answers."
