"Edwards, you--er--are a bit disconcerting.

I presume you know that the rules require you to be in bed with lights out at ten-thirty ?" "Yes, sir." "Hm! And you--er--deliberately transgressed that rule ?" "I didn't see anything else to do, Mr.Daley.You said I must turn that in by noon and there wouldn't have been time this morning to do it." "Logically reasoned, my boy, but----" The instructor shook his head.
"You mustn't expect me to compliment you on your performance, Edwards.
To perform one duty by neglecting another is hardly--er--commendable.

If it were not that you had transgressed a rule of the school, Edwards, I might compliment you quite highly.

Your composition--I--er--I've been glancing through it--is really very good.

I don't mean that you have not made mistakes of grammar, for you have, lots of them, but--er--you have written a well-constructed and--er--well-expressed narrative.
