The weather forecast for today doesn't look great, so I'm putting off my long walk until Thursday. Today we're expecting thunderstorms from 11am onward, and it's going to be a warm and sticky 26°C; Thursday's forecast is for partly sunny skies, dry 22°C air.
I've met people who do athletic things in all conditions, and I don't understand why. I want to enjoy the walk. So, it's no big deal to postpone it until there's a much higher likelihood of good weather.
