He is a composed and smiling man, prompt to irony, sometimes almost to black humor. He likes to laugh and his companion in the matter is nearly always Professor Ackland. They complete each other in winks and private jokes. Even though they eat with the rest of the School in the Great Hall, they are always side by side, accomplices, whatever they're up to.
Endowed with a great charm, Professor Fry plays with his negligent ways. When he moves to the next lesson, however as dirty as the previous one, he finds no reason to change his robes full of earth, hair or slave. Even if between two lessons he must have lunch. He has class, even so.
A lesson with him is more serious than seems believable. Concentrated and ready to give examples, he is a good teacher, although not hesitating to scare his students sometimes, to prove the famous saying right, 'more shaken up than harmed'. He is never dangerous, at least not before OWLs. He sometimes amuses himself by watching the frightened look on his pupils' faces. But he reassures them quickly as he is conscious of their unrest. It never lasts long. One quickly knows what to do and there has never been an accident in Professor Fry's lessons.
