Rainy Days:

PRO:  I don't have to water anyone's flowers (including my own)
There are less people on the street to maneuver around
I get to wear my awesome rain boots

CON:  Everything smells like wet dog (including me)
 Too many people on the bus
Trying to unlock a door with a dog in one hand and an umbrella in the other (multitaskapus)
I HAVE to wear my awesome rain boots even though it's humid and gross
