they won't waste an offer
Agreed. Last year at the Channing interview we clearly picked up on the headmistress sounding us out about why we'd choose Channing over Habs or St Albans, especially as we lived nearer the other two. And in fact DD got offers from the other two and was waitlisted at Channing. We accepted Habs and then Channing said in May that we hadn't been successful. So if for geographic or other reasons you'd really prefer Channing, tell them, and make some NLCS-waitlisted girl very happy!! But if you're much nearer NLCS and St Albans, they'll have taken that into consideration.
