Which means : Happy Supernatural Day ! ! ! ! ! After being in a crappy , pissy mood all day yesterday , I ' m in quite a good mood today . I had one more meeting with my adviser , who said that basically I only have little things to work out and fix in my thesis before I turn it in ! I was so afraid she was going to say I needed to re - work my conclusion ( again ) and was dreading doing everything at the last minute .

Question: How many times must have I reworked the conclusion on my thesis before this ?
Answer: I must have reworked the thesis at least twice before .I must have reworked the thesis at least thrice before .I must have never reworked the thesis before .I must have reworked the thesis at least once before .
