I don’t believe you are interpreting the posts correctly. My take (and my position as well) is that people just think that a 13 year old homeschooled kid is not necessarily ready for the college environment. There are numerous reasons for this. The entire social aspect of college is going to be forfeited because the 13 year old is too young to participate in a lot of the activities on the same level (and no, I am not talking about drinking or immoral behavior).
I didn’t participate in any social activities on campus in all the years I commuted to college. I never wanted to. I had my own life and went to college for an education.
And that was as true at 18 as at 32.
I’ve been to three different colleges and have never seen the kinds of things go on that people here seem to think is in store for this girl and I’ve never seen the kind of immature, junior-highish behavior that others seem to be expecting out of your average college student.
