Lately, he's been having a trouble with being home on time. You kind of understand it - he has a lot of things going on - and you're happy that he spends a lot of time out of doors. On the other hand, you believe learning to be timely is very important, and you see his tardiness as rude to the rest of the family, as it often means you have to make some kind of accommodation for him. The last time he was late, you spelled it out very specifically that if he did not have approval to be out late, then he had to be home on time, and if he wasn't, he'd be sore as well as late.
Today, you got home a few minutes before Greg was supposed to be home. He wasn't there yet, and by the time he arrived, he was almost thirty minutes late. You tell him to go to his room and get ready for his whupping, and you'd be up in a minute to administer it. He protests he was late because of Scouts, and he was working with some of the newer kids. You remind him that he's been specifically told that he can't stay late without permission. He explains that he just couldn't leave, so he called you. When you didn't answer, he texts you. You know that's not true - at least until you check your phone and realize it ran out of power at some point this afternoon.
Does Greg get a pass or does 'not without permission' mean exactly that?
