^^I find that quirky and non-quirky people often couple, and some even do it quite well. World goes round and round.
The year my son considered W&M there were pictures of a lot of blond kids in polo shirts and chinos and popped colors on the website. He instantly labeled it as too preppy and didn’t apply. I’ve been assured that his impression was totally off, but in the end he had good choices so all’s well that ends well.
I think that Tufts is so quirky that they view “mainstream” as just another form of “quirky”.
