One day, a science teacher teaches the students on how to test the acidity of urine. Now there's a container which contains 10ml of urine on every student's table. After all the apparatus is ready, then the class starts.
Teacher: All right, class. Now let me show you how to test it. First of all, put all the apparatus away, except the container which contains urine. Then, dip your finger into the urine. Watch carefully..
(The teacher puts his finger into his mouth and all the students are stunned by his action.)
Teacher: OK, now it's your turn. Try to do what as I did just now.
(Even though every student thinks that the test is so ridiculous, they have to do it as what the teacher did. And.. they did it.)
Students: Yuck~! It's disgusting!
(The commotion occurs in the class. When the teacher sees what they did. He explains to them.)
Teacher: Class, please calm down and relax. OK, let me tell you the truth. Actually I was using my middle finger to dip into the urine and put my index finger into my mouth. So, I'm not really taste the urine and I'm so disappointed what you all did. You know, observation is very important, no matter it's on the test or in your life. If you lack of observation in your life, you will miss something. So, next time please concentrate and observe.
(After the explanation, all the students smile and nod.)
So, you too. Try to observe everything in your life so that you won't miss something or something which is important to you.
