burying my face into the cool sheets of my bed , exhaustion weighed me down.i should n't be tired ... it had been morning when i left alexandria and it was only early afternoon now.but i felt as though i had been awake for weeks , as though i was experiencing a two-thousand year jetlag.i could n't keep my eyes open.before i could think even one more coherent thought , my heavy eyelids fluttered closed and i slept a dreamless sleep .
