Today's scenario: you are warm and cozy in a tasty-soft bed...and the alarm clock rings. Never mind you set it for a quarter to six and went to sleep murmuring "I WILL get up when my alarm goes off", you reach out and bap it. Now the little feet will depress...here's where something magical occurs. Snooze.
Some people only wake up once a day. I woke up over 6 times this morning. Imagine what the can do to someones psyche! So when I finally DID get up (6:20) and had to leave (6:30), I still had time to throw on my clothes and walk the mile to my destination. My point? Timed sleeping in. I have yet to discuss this concept with my roommate, but I'm sure she'll be fine with it.
