^^^LOL. That's funny, though not so far fetched!~
I don't know this for sure, as I am not on facebook, but I think my older D may have it on some privacy setting and I wonder if it is due to being a grad school applicant. She is not one to have inappropriate stuff of her own choosing on a personal site. I just know her this way. But on facebook, others can post pictures on your page or leave messages and so forth, that you do not entirely control.
Also, while I thought her name is not a typical one, I think there is another college student on facebook with her name and a high school student as well. Hopefully, any important person who does this search will realize those kids aren't her. I'd like to think that could be easy to determine as the college name is different, as is the grad year and one is a high schooler. But ya gotta wonder.
