(Encouraging)  Everything checks out. Grades are high, punctuality is outstanding. Your future looks bright, Mr Parker.

(Disappointed / Lecturing)  Not only have you missed class, you went out of your way to miss a final. And since this was your first assessment Mr Parker, this doesn't look good on you at all! We pride ourselves of excellence here, which means at the very minimum showing up on time. We can consider a reapplication next semester, but I can't guarantee you'll be successful.

(Explaining)  This is our pristine Mechanics and Engineering lab. Some of the brightest minds have worked in here. Including Hank McCoy and even Tony Stark.
