This reminded me of a completely different conversation I'd had a couple weeks back with another mom of a girl scout, she was asking about dd's grade, then age, then very specifically her birth month..I was really not sure what she was getting at
One of the moms in DD7's class approached me at a school event last night, and the conversation went like this:
Her: Is that your daughter?
Me: Yes.
Her: How old is she?
Me: Seven
Her: She must be very advanced.
Me: She skipped 2nd.
Her: Yeah, [her son] told me.
It turned out that she was trying to figure out if DD had been held back earlier, then skipped to catch up with her age-mates. Her son (whom I'd thought was young-for-grade, based on his size and behavior, although he's clearly very, very smart) had repeated pre-K for non-academic reasons and was actually old-for-grade.
