At a site recently I would run into this one lady often as we worked in the same atco-hut-make-believe-office, but she had nothing to do with the job I was there for. Going by my own philosophy, I would smile to her in the corridors (or in between cubicles) and do the small talk in the kitchen when getting a cup of tea. But I was stuck, now every time after that I had to smile and say hello.
I could pass her up to five times a day, and obligated to say hello to her every time. Sometimes I would even bust out the "long time no see" joke, which is a winner if you want polite laughter and nothing more.
I have no idea what her name was, or probably still is, nor do I feel I need to know. It will just descend into an awkward situation for some reason or another I can tell. I probably overlooked her one day when distracted by thought and automatically be an arse. She did suffer from ducks disease, so very easy to overlook.
I do not want to be an arse Sam I am, I rely on people liking me for performance reviews, and I do genuinely find people interesting. The only thing I could do is just to keep smiling. Smile like a maniac at everyone even when half a shit day has passed and the afternoon forecast is worse. So yeah, take that lady; even if you are having a bad day, you’re going to cop one of these bad boys :)
