This story took place in Israel.
One day when some government officials were rebuilding a barn,they found a mouse hole and used smoke to force the mice out.Later they indeed saw mice running out,one after another.
Then,thinking all the mice had escaped,the officials started to clean up.They saw two mice squeezing(挤)out of the hole.The strange thing was that they did not run away immediately.Instead,one chased after the other near the exit of the hole.It seemed that one was trying to bite the tail of the other.
Everyone stepped closer to take a look.They realized that one of the mice was blind and the other was trying to allow the one that could not see to bite on his tail so he could help him escape.
Witnessing what happened,everyone was speechless and lost in thought.
