Forgiveness at the Gas Pump

I pull up to the gas station this evening and start pumping gas. I look to the next pump over and my heart skips a beat. The guy I see there looks just like a guy I use to work with a few years ago. This is not just any guy, but a guy who verbally abused me and harassed me day in and day out at my job. I remember going home crying from work because of this guy. He was cruel, rude, unprofessional, and verbally abusive. I remember trying everything in my might to shower this guy with kindness to try and win him over so our work environment could be more peaceful. Nothing worked. Eventually, I left the job almost solely because of this abusive workplace environment. Back at the gas station, my heart skipped a beat thinking it was him. I looked away quickly and focused on the pump, having flash backs to interactions with him, thinking about what I should say to him in case he noticed me. The words coming to my mind were not nice, forgiving, or Christ-like. I built up enough guts to directly glance back at him to confirm if it was him or not.
