It was raining in dc the other day and I as I went down in the elevator (in rain gear, bike garb, helmet on) a person in the elevator says to me with a shocked look on her face It's raining...what are you going to do? I look back and say, I have a rain jacket on, and if I get wet, it's not like I'm going to melt and die. She had for a brief moment an epiphany-esque look on her face as she perhaps realized that getting wet isn't the end of the world.
I've always wondered at what point in our lives getting wet becomes a disaster. Kids will play in the rain just long as the sun unless they constantly hear Get inside. It's raining! At somepoint we just lose that. We decide we have to run to get out of it, carry umbrellas around in the car, etc.
I have to admit that commuting in the rain and occassional snow are my favorite commuting days of all.
