two farmers had a big horse. this was fifty years ago when farmers used horses a lot. the horse worked in the fields in the day and slept in a stable at night.
the horse was a big animal, and the entrance of its stable was too low. when the horse went in or out, its ears hit the top of the entrance. the horse did not like this. it got angry and often kicked the farmers.
'what can we do about this problem?' they often asked.
after a long time, one of them thought of an answer.
he said, 'let's cut away the top of the entrance. then the entrance will be higher.'
so they found a saw and started cutting. their saw was old and not very good, so the work was hard. after a few minutes, a friend came to see them.
'what are you doing?' their friend asked.
the farmers told him about the problem.
the friend said, 'you don't have to cut the entrance with a saw. you can dig the entrance with a spade. then the floor will be lower. that'll be easier and quicker.'
the farmers thanked their friend, and he went away.
then one farmer said to the other, 'that man's stupid.
the horse's ears are the problem, not its feet.'​
