The context of the following conversation is Addison made sure they were on time by getting a good nights sleep and setting two alarms.:
Addison says My roommate and I were fifteen minutes early for class today..
The friend responds Wow, that's impressive, considering the fact that you two usually go to bed so late..
Addison responds No, I was determined to be on time for this class. I went to sleep at 8pm and set two alarms for the morning..
The friend responds But you usually sleep through your alarms..
Addison responds Going to bed at an earlier time helped me feel much more awake and refreshed..
The friend responds I guess that makes sense. I'm just glad I don't have to share the first fifteen minutes' worth of class notes with you today, since you were on time for once..
