So this particular morning, I went to the gas station behind me was this awfully rude car (driver was overtaking me and it somehow got me a lil pissed). So he pulled beside me. It was an elderly man, reminded me of my late grandfather. I was somewhat angry that he made the move to overtake me but I was in a jubilant mood that morning (since Arsenal just won!!). I actually smiled at this elderly man, he had a lil frown on his face as he got out of the car. I could've been really rude and pouted at him but I didn't.
Getting back to my car, I do what most people do at gas station, pump the gas. And little did I know that bitter looking elderly man actually smiled back at me and asked me how I was that morning. :) That actually made me smile, and we actually chatted for like 2 minutes. And he told me he just took his children to school. He also made a joke about cars and gas. LOL I don't remember what it was but it was funny at the time.
So yeah my point is, a smile can go a long way :). Who knows, someone would want to trade your smile for a thought. <3
