Text: My husband says they have two or three each week at his place of business (woman pregnant, just gave birth, going to be engaged, married, found a lover, etc.) and he has to chip in $10 for every celebration.
Entailment: My husband claims that there are two or three parties at work every week and he always has to chip in $10 to help pay for the celebration.
Contradiction: My husband doesn't have to pitch in any money for any parties at work.
