This is something my kid might be telling me if he gets ahold of my computer...
Dear Mommy and Daddy,
Can I please go night-night at 6:30 tonight instead of at 6:00? I know I usually have to go at 6:00, but I'm really tired and I feel like I need a little extra time to rest. Plus, I'll be able to wake up feeling more better and ready for tomorrow.
I promise I'll still be awake and ready for school in the morning, and I'll make sure to get all my homework done before night-night time.
Please can I stay up a little bit longer tonight? I really want to get some extra rest.
Sincerely,
[Your Name]
