Take a shower before a rainy commute ...
I work in a home office now, but for over 5 years I worked in a building without showers. Every day I'd shower before biking 9 miles to work, including mornings when it raining. This morning I had an errand to run in the morning, and it's forecast to rain all day. I take my morning shower like every other day, knowing I'm gonna get soaked biking 13 miles. Always seemed like a waste back then and still does today.
Anybody else shower in the morning, even though you know you're gonna be a mess when you get to work?
