I've always said that you don't have to dress badly just because you live on a farm. I've tried to avoid wearing mud (or worse) encrusted boots to the grocery store. If I go out for lunch with some friends and then have to do chores afterwards, I bring clothes to change into.
Sometimes, I think I take it too far though.*
You don't want to know what's on my shoe.
*In my defense, Henry said that the paths were fine, and we were planning on going out to dinner afterwards.
