Like memories in cold decay

I'm the kind of girl who's active at night. Not nocturnal, not whereby I sleep in the day and not sleep at night. But just active at night. Because that's when my whole family, except my bro is at home. So I mainly have lots of fun especially at night. But last night, before sleeping, while lying on the bed. I kept talking to my sis and making noises, then after awhile I realised that there was silence on the other side. She fell asleep :(
