I Cheated At Work Bingo

Last Friday during our work team-building day, we had bingo where everyone got silly prizes. I was lagging behind and thought 'screw it,' so I snuck a peek at my coworker's card to see what numbers they needed. When they called out the last square I needed to win, I pretended to be excited as if lightning struck me with luck. My team even gave me weird looks but congratulated me anyway. Today when we debriefed it, I just shrugged and said I was lucky, I couldn't admit I cheated, could I?
