kariya : teacher can i use the bathroom?
teacher : i don't know, can you? *sounded like mocking him*
"students start laughing"
teacher: quiet
kariya : *sigh* and start talking. when i was using "can" i was using its secondary model form as a verbal modifier asking for permission, as opposed to expressing ability. I thought since you were a teacher you'd know that
"they were surprised by what kariya said"
kariya : so can i used the bathroom now?
teacher : yes you may go now
kariya : thank you
