Whether be the weather

It had gotten cold and suddenly it's sort of warm again: high of 74° and sunnyish. I think to myself: I should ride my bike to work since this might be my last chance before the true cold comes. But I tell myself I need to replace the chain, that I'll hate riding home this evening as it starts to get dark. And so I tell myself that I will bike this weekend, to the library, the city, a museum. But I check the weather. There is an expected 20° temperature drop and rain. Rain. To add further rust to my bicycle chain.
