"The Noticeable Conduct of Professor Chadd" is a Story by G. K. Chesterton. First appeared in Harper's Weekly (June 25 1904). Basil Grant finds out why Professor Chadd insists on dancing.Basil Grant had comparatively few friends besides myself; yet he was the reverse of an unsociable man. He would talk to any one anywhere, and talk not only well but with perfectly genuine concern and enthusiasm for that person's affairs.
