Free Haircut<br>Jim didn't want to spend 20 dollars for a haircut. And he didn't think cutting his own hair would be that hard. But after several minutes of cutting, his hair looked terrible. And he decided to just shave it all off. Afterwards, Jim always paid to have someone else cut his hair.
Jim didn't go to a barber.
This statement is true because he decided to cut his own hair instead of going to a barber; it may be difficult because the word "barber" was never mentioned, or because it was unclear if he didn't go that time vs not going any time before that.
