"It's awfully considerate of you to think of me here
And I'm much obliged to you for making it clear that I'm not here. "
That perfectly describes this week for me: back from the seaside after a week's break, for a week's work, while the rest of the family is still at the seaside and having a good time. I'm rejoining them next week. Only my body is at work, my mind isn't... :-\
But like Chris Rea said: "Sometimes I'd swear this body's got a mind of it's own" ?
