Respectfully snipped for focus.
I didn't see anyone "refuting" anything, just trying to be helpful within the context, when exactitude is not especially crucial. If the reference is to wenwe's posts in particular, in my experience over the years, his/her posts are always on point and well-articulated: I think you can expect him/her to be diligent about being precise when the discussion calls for it.
Back to Tylee. Since there were other options for college-level work in Rexburg, and Tylee seems to have had no problem getting around since she had a car, the important element IMO is not whether or not she was going to attend college in 2019, but rather if she was going to school of some sort at all. If not, what was the poor child doing all day? Who was helping her in any way? Did she have anyone to talk to? She went missing for weeks, and no one noticed? IMO
