I sent my sister upstairs to my bedroom around 10pm and printed coloring sheets so she can do something artistic for baby k and its cold downstairs and I have a heater in my room so she could stay warm and so I stay downstairs and continue doing school work... Go upstairs at midnight to find her sleeping in my bed, and she looks to comfy to wake up so I am downstairs freezing cold with david and starting to get tired... I don't wanna be the mean sister but I'm about to wake her up and make her either A) move over so me and david can both fit in bed or B) wake her up and send her to the floor.
