Mason had placed his arm on his desk and rested his head on it as he held back a yawn. Had he been a first year, Mason would have thought that the sudden appearing of the Professor was amazingly magical. But as a sixth year now it was mweh... Not so impressive.

Still, since this meant that class had officially started, the Ravenclaw moved to sit upright to give his full attention. Dissilusionment charm...he had never tried it before himself, and any chance to learn something new was something he enjoyed however, looking at the basket of eggs, he had the feeling they were going to smack the eggs on their heads to get the 'feeling' of the charm.

Or he was over-thinking and they were going to practise the charm on the eggs...
