Mr. Smith is reminding his son of his curfew time. “Don’t forget, Paul, be home by 10:30 p.m.” Describe nonverbal cues that would create a mixed message and convey the idea that Paul’s dad is unsure about the curfew time and wouldn’t be upset if Paul came home late.
That means you would have to be home by approximately 10 mins early so you'll have to be there BY 10:30 not just 10:30 so you should show up by 10:20pm so you wont be late.
