“Better be careful professor.  Wouldn’t want to make my already over-inflated ego get any bigger.  My head might explode,” Harry joked, using the words he heard so often from Snape’s mouth. 

Snape let out a laugh and then froze along with Harry.  Harry’s jaw dropped as he stared at his professor, who had a horrified look on his face.  They were both officially spooked and beginning to think they had temporarily lost their minds.  There was no denying it though, Snape had laughed, not sarcastically, for one of the few times in his life. 

Harry gulped.  “Did you just….”

“No.”

“Yes you did, you just…”

“No, I didn’t,” Snape growled. 

“Okay.”
