Tired

by BlobDude

"You're tired."It wasn't a question. It wasn't even a guess. It was a cold hard fact, one that made you embarrassed that your (admittedly poor) attempt at hiding it was so unsuccessful the skeleton who hardly even looked up from his laptop noticed. With a smile that trembled and didn't meet your eyes you shrugged a bit, slouching in the chair you were sitting in. "I'm fine."
