You didn't bring your phone (it's still charging), and you don't have a watch, so you can't tell the time right now, but you vaguely remember seeing it was 4:13 earlier, and it has been a couple minutes, so you guess it's around 4:30. It could be 4:20, but you don't know why that'd be any funny. You instead just put back the guitar, getting ready for the next command.
