"After picking up the drink, I make my way back to the gym, now empty of students. Coach is waiting for me at her office door."Took you long enough," ...he carps, snatching the drink and envelope with one hand and thrusting a bundle of loose sheets at me with the other."Get these stats in the database and if anybody's looking for me I'm not here, right?"
