"He's going to investigate.
And I'm afraid his hot head will get him into some sort of trouble, too." The imposition of the silence did not affect Greg in his relations with his tentmate.

When a cadet is sent to Coventry, or has the silence "put" on him, his tentmate or roommate may still talk unreservedly with him without fear of incurring class disfavor.
To impose the rule of silence on the tentmate or roommate of the rebuked one would be to punish an innocent man along with the guilty one.
Rarely, after all, does the corps err in its judgment when Coventry or the silence is meted out.

Many cadets of the first and third classes had already gone to meet girls whom they would escort in strolling near the bandstand.

Plebes are not expected to escort young ladies to these concerts.
