"No," Tiffany said. "I've just been feeling weird all morning. Hope I'm not getting sick."
"Well, get away from me...I don't want to catch a cold or flu or something," Sarah said, backing up. She hated being sick.
But Tiffany had, in fact, been sick for a long while. She wasn't actually feeling weird because she was becoming sick, she was actually finally recovering from a rare disease no one even knew she had.
The symptoms of this disease included loss of concentration and disorientation, changes in mood...
Not only was Tiffany now recovering, but, since she didn't know she had it, she didn't know she had infected two other people...and neither did they.
