h'okai!
So, Mary didn't leave her dorm at all yesterday, and after Dorcas' howler that probably the entire freaking castle heard, she's not leaving it today, either.
If one of her roomies or Lily or Esme or another Gryff girl could bring her food today, she'd really appreciate it. :)
... I imagine the professors can figure out why Miss Macdonald hasn't been to classes yesterday or today, going by Dorcas' howler? xD
