We have a large experience of them in the travelling season.
They all come with their own private suspicion of us lurking about the corners of their eyes.

They see everything we have to show them, and eat and drink at our table, and join in our amusements, and get as pleasant and friendly with us as can be.

The time comes to say goodbye--and then we find them out.

If a guest who has been laughing and enjoying himself all day, suddenly becomes serious when he takes his leave, and shows that little lurking devil of suspicion again about the corners of his eyes--it's ten chances to one that he's a clergyman.

No offence, Mr.
Hethcote! I acknowledge with pleasure that the corners of _your_ eyes are clear again.
