The fact her ball wasn't working, the music was so soothing and the place so dimly lit were not doing the Gryffindor any favours. Surely there was only one thing to do but she imagined it would be extremely bad form for the Head Girl to fall asleep in the middle of a lesson; no matter how comfy she felt in her pajamas.

She could feel her eyelids dipping on the odd occasion but for the most part she was resolved to stay awake. It was the least she could do in a world where courtesies were everything.

Perhaps she would just focus on clearing her mind. Thinking about absolutely nothing. That might do the trick. Merlin knew nothing else was. The only problem came with the fact that the less she thought was the more she felt herself drifting....off to sleep. It didn't take a fancy pants Diviner to know this wasn't what the Professor had meant when she gave her instructions so Lex sat a little straighter, shifting some on her cushion (which wasn't helping either).

Her mind was clear but then visions of little candy canes and chocolate frogs danced in her head.

Must. Not. Sleep.
