Here's a positive: the company shirt sizes run big so I'm wearing a medium. It's the first time in my life I can wear a medium.
Now look at that, already you're thinking positively.
See what coming here and griping does for the soul?
And when you think it can't get any worse, picture the people who are making your day miserable naked. That is usually all it takes to get a smile from me.
Or a grimace. Depends on the age, weight, etc. At the very least, you'll forget what made you miserable for a few minutes.
