many people love their kidneys,but i didn’t love my kidneys when i was young because they couldn’t support me in long—distance running exam ,as a result,i didn’t get a good grade in PE exam. they were so weak and lazy.however,i regret that i have misunderstood my kidneys for so many years now.they are not as lazy as i thought,although they are very weak,they are very hard—working instead of being lazy.when i stood on the playground and ready to run,my kidneys tried their best to support me,the weaker they were,the harder they worked. feel sorry about my kidneys,if i still have the chance to get along with my kidneys,i will love them all day and all night……
