...when DH walked into the house yesterday afternoon looking like this:
He'd spent most of the day under the kitchen laboriously working on leveling the kitchen floor. It wasn't muddy under there; just dirty and hot. However, dirt + sweat = muddy clothes.
I am very thankful to have a DH who can do just about anything that needs doing around the house, and that doesn't mind (too much) doing what he calls grunge work - getting really sweaty and dirty. (And I'm REALLY thankful for my washing machine!)
