An Ivy.
Ok, not really. Obviously I wouldn't forbid that
But I do think that Ivies are pretty overrated, and the degree of competition among the students is ridiculous and unnecessary at many of them. Also, many Ivy-goers I've talked to seem really unhappy in general. Yes, of course they're getting a great education. But I think the "warm fuzzy" factor and loving your alma mater is so important, and I think that's more prevalent at non-Ivies that are still great schools.
But if my future kids are brilliant and will survive in a pressure cooker, I suppose they could go. As long as they didn't choose their school based on its name alone!
