((Ugh, I'm really sick at the moment with a sore throat, so I feel like making Ginny sick.))
Ginny had only meant to step into the Hufflepuff common room for a moment. Just to replace a book she had found in the hallway. But when she turned to leave, she started coughing. She had been coughing for a few days now, and this particular coughing fit put her on her knees.
It takes alot of energy to stand up and cough, and so she pulled herself up long enough to flop on a couch. After a minute or so, she stopped coughing and just lay still.
