Even though I certainly enjoy sunny days, I also recognize the importance of rainy days as well. Without the rain, we would be living in a cinder. Granted, as I tend to work and play indoors more often than not, I'm not as affected by the rain either. Still, we need balance: enough sun to keep us happy and enough rain to keep us from frying.
As I'm writing this, I realize that there's a metaphor to be made here as well. However, as I've been reading a lot of stretched metaphors lately, I think I'll let everyone come to their own conclusions.
