Sometimes it's during the day. But M-F I'm at work during the DAY hours.
Last night, well, this morning, at 1AM, my son was STILL up, refusing to go to sleep. I got on him and said 'Lay your butt down NOW; it's bed time' and they started hissing. They were awake playing when this happened. I just looked at them and said 'aren't you lucky you're allowed to be up this late!?' and laughed. They kinda cocked their heads at me and went back to playing.
