Last month, I had a conversation with a new coworker that was a bit odd. We were chatting about our kids, and after telling me about how great a mother she is (she literally used that expression) to her sons, we got to talking about my daughter. She asked if I would ever allow my daughter to date. I said, um, sure, when she's old enough, like 15 or so. Coworker was aghast! See, in her culture, girls don't date, they get married. In order to even consider being allowed to see a boy, she said girls basically have to be "pre-engaged" to him but regular dating? Especially casual dating? Nope, doesn't happen.
It was her reaction that was brain-hurty: She seemed by turns fascinated and horrified that I thought it would be acceptable to let my daughter go on dates (eventually, years from now). She's lived in the US for at least a decade though, and I'm guessing has been exposed to enough of our pop culture to know that dating is common here, starting in high (or even junior high) school and continuing, well, indefinitely in some cases, but certainly preceding marriage in most cases.
