Re: s'okay!
I think I shall return home this evening. I left in quite a bit of haste, and did not even have a chance to change out of my painting smock. [he tugs at the pillowcase a bit] Had there been any premeditation to my exit, I might have remembered to bring a change of clothes, and perhaps my tooth-brush.
Watching the rest of your students practicing may help take my mind off of this disaster for a little while. That is what sports are good for, isn't it?
