Busted

Bill just came through my bedroom door and caught me sewing, plus running the electric heater in my bathroom before going to bed.
So now I am in trouble because I went to bed an hour ago and shut the bedroom door but didn't go to sleep. What an ass; why does he think he is in charge of whether and when  I go to bed? I can't even imagine thinking I needed to monitor when another adult went to bed. That is what doors are for; so a person can do what they like without bothering anybody else.
