The Connecticut Post writer is playing mind games with his readers. When it came to selecting a college, Rog, a high school student, had not "changed his minded." He changed his mind. I suppose the kid had a change of hearted. Not that I mind.
I've heard the expression "drop the pretense." How about "drop the past tense"? In this case, the -ed. It would put my mind at ease if we could get rid of this suffix. Too late, I suppose. I'll have to put it out of my mind. I guess I can do that ... if I set my mind to it.
