It’s already in her mind, otherwise she would not have posted the original query. Here’s the question: with a decent local option, is Emma Willard worth a “huge portion” of her family’s income? I suppose the answer might depend on how huge is “huge.” If it’s greater than, say, 60%, and, as a result, the family’s financial security is threatened, and there are no non-educational reasons for her to attend high school abroad, I say the answer is no. But I’m just a stranger on the Internet; the family will do what it wants.
