[Ghost in the attic]

I went to an interview about an O&G job (on internship from school), and was talking about past experience with operating in camps.

Interviewer: "Was it a pretty dry camp?"
Me: "It was supposed to be, but our boss always brought in the odd case"
Interviewer: "I was talking about precipitation"
Me: *laughter*..."oops"
Interview: *silence*
Me: *silence*


I didnt get it.
