Today I suffered at the hands of a manky stain on my shirt cuff. It was white and looked like something bodily and embarrassing from a distance. Up close it looked like what it was, chewing gum. I'm not sure how it got there and by the time I noticed it I was out of the house and unable to change.
Something like that can really damage your mojo. It's tempting when you talk to people to make excuses for it but then you run the risk of highlighting it.
I soldiered on.
