A pair of friends went on a trip.
On the way, they saw an axe on the ground. While one was thinking of picking it up silently, the other suddenly shouted, 'Oh! We have found an axe.'
The person that held the axe in his hand said angrily, 'I saw it first, so you should say: "YOU have found an axe" instead.'
While the other person was feeling sulky, they realized the man who had lost the axe was catching up with them. At the moment, the one holding the axe said, 'Gosh! We can't run away!'
The other caught the chance and said, 'Oh, no! Not "we can't run away". You'll have to say, "I can't run away."'
