Text: yeah the only thing you've got to watch is when that creek comes up we camped next to one one time when we were there a couple of summers ago and we figured we were up a long way off and then it rained that night and we thought well wonder how far off we are and we got up the next day and that creek that had been fifty or sixty feet from our site of our tent was now about three feet away and it's like oh well maybe we ought to move just a touch so that was kind of funny
Entailment: You have to watch when the creek comes up.
Contradiction: The creek never comes up.
