Well...the best thing to do is to tell yourself that it could have been worse.
It could have been ten miles...or 20 miles.
It could have be snowing and you could have been without a coat.
No matter how bad a situation is it can always get worse.
I love walking in the rain anyway...I find it run for some reason. Plus, when it's raining there are less psychotic idiots outside spouting nonsense. Less noise and I can walk at whatever pace I want b/c there are no fat people walking extremely slowly all over the place. Living in a big city it's awful sometimes.
