I have a funny story about early guests. When DH and I were newlyweds, we were hosting a small get-together at our tiny city apartment, and the guests included the new pastor of our church (an older man/experienced pastor, but new to our church), and his wife.
Due to the long trip required on public transportation, they arrived about 15 minutes early. Now, about 20 minutes before the start time, DH and I realized we had been so busy getting the apartment/food ready, neither of us had showered or dressed. We decided to double-up and "save time and water".
About 5 minutes later we realize the doorbell is ringing and someone is knocking. While I go to peer around the door in my towel, sopping wet, DH is scooting through the bedroom/sitting room in his towel, grabbing clothes. Pastor took one look and said, "We'll come back later." I wanted to shout, "no, really! cleanliness, that's it!" But of course, that would have just made it worse.
