Agree that it was probably a verbal exchange. But I have only seen those things pan out, not get back-tracked. In fact, I know two girls who were just sophomores in high school when they—whatever word you want to use—-committed? Agreed to attend?—one to Harvard and one to Princeton. And those are the schools they currently attend. Of course if they committed a crime or had completely bombed the rest of high school, they would not be there, but in my experience those “offers” are only made when things look like they absolutely should happen. I have never seen that stuff rescinded, although of course it’s possible.
