If it's a kid, I can understand and good luck. But if he's an adult, then why can't he wake up by himself and be responsible for himself, like by using an alarm or something like that?

i ended up falling asleep anyways but hes a teen, i tried to have him set an alarm but he said that ¨doesnt work¨ and he cant wake up to alarms, a bit silly imo but i understand kinda; i used to be the same with alarms

Yeah ok, teens are the weird stage in between, sometimes it works and sometimes it doesn't. Hope you woke up in time.
