Darren is not the sort of guy who attracts a lot of attention to himself. I'm actually struggling to remember any specific stories or events involving Darren. He's just always there in class (or not. I actually think I've signed more absentee notes for Darren than any other student), quietly working away.
It seems like, in the four years I have taught him, that Darren has always sat at the back. He's always kept a low profile. He's always worked away independently, sometimes falling a little behind, but always working hard to get caught up.
You were an easy student to teach Darren! Thanks for all your effort and determination. Enjoy your upcoming graduation!
