I saw a big smile on my face.
I felt and looked bloated from the heat, my toe joint decided it was time for some intense pain and I couldn't stand comfortably, the air con was broken and the windows didn't open, and all I could see was a sweaty, fat, overheated, cranky figure in the mirror trying to knock out a few bent-over rows. I finished my second work set with a conversation to myself about just shutting up and doing the work, and a stranger walked past with a loud, "GREAT WORK!" and he made eye contact to make sure I had heard. I forgot everything for a moment, grinned back and made some lame comment like, "Didn't bloody feel like it," but inside it made my day.
