2T4U/Jack/Morning/She still sleeping soundly in her bed, just like you expected
< 2T4U
You approach your soundly sleeping little 6 year old sister, chuckling to yourself. You are always amused by how deep that kid sleeps. Once, you dropped an entire stack of cookie trays downstairs and she didn't even stir. The kid sleeps like the dead, but she will wake up very quickly if she hears a family member's voice (although a little shaking helps.) You don't even have to talk very loud, it is the most amazing thing.
You remember back to some cruel experiments you used to do to test just how far this went. Once, you even lifted her up and put her in her toy-box and she didn't even stir.
