I work second shift as a semi local driver. I have to load and unload my own cargo each night. Yesterday one of my coworkers made it a point to stop and ask if I was okay. He said I seemed to be upset. It was only then that I realized I was being a bit rough with my mood and it was because of the heat. I'm a big guy for starters, plus I take meds that make it difficult to tolerate the higher temperatures. I'm normally a happy guy (well that's the mask I wear around others) but I didn't realize my mask had slipped. Just because I was hot and miserable, doesn't mean I need to act miserable. #inspiration source
