When your backpack is too light

The alarm on my phone starts ringing at 06:30 with the melodious tune entitled "motorhighway.aac". I hit the snooze button with sniper precision and doze back again. I hit the snooze button five minutes later. And five minutes later. In the end I extract myself from bed fearing Marian's kicks and/or comments. I have a gut feeling though, and move the curtain a bit and try to peer outside. I will my right eye into opening and realize that the fog I am seeing is for real and not due to my shut eye-lashes. To be sure, I open the window and throw my hand outside. I mutter a satisfied "YES!" and perform a double somersault back to bed.

This is what happens when your backpack is too light and you think you can actually RUN uphill.
