Rain Coat

Okie, as my kind sis offer to fetch me home from work yesterday as it's raining (yup, i ride to work..), she commended in a mono tone, 'If u don't wanna buy a rain coat, might as well don't ride.' -----> Em, any link?? I can juz NOT ride during raining days right?? So, does it mean that if i don't have a streets directory, don't drive?? Or, if i don't have a 'bird', don't wear pants?? -_-;;
