Text: they came in and did it and left in just no time at all and i think it's because they you know they were accustomed to working in that  environment in those particular condominiums and i don't i didn't watch them but i couldn't imagine that they came in and painted it the whole ceiling you know just within a couple of hours
Entailment: I did not watch them work, but I think they painted the ceiling in a couple of hours.
Contradiction: I watched them paint the whole time, and it was fascinating.
