Like A Liar

Do you ever feel like a liar?
I ever felt it, make me so confused and guilty.

Today at school, the bell was ringing. My teacher entered the class. She gave us motivation in order we pushed ourselves to study study study to get our dreams. Then, she taught the lesson. She also asked to us about our task from her.
       "I hadn't found anyone to memorize fifty Physics Formulas till right now," she said.
       "Anyone had memorized it?" she added.
       "That's our task. I must memorize it somehow and I had memorized it certainly," I said in my mind while rise   my hand.
       "Do you had memorized it?" she said and look at me sternly.
       "Yes, Mam!" I answered her.
       "Why don't you meet me to show your memorized?" she queried to me.
       "I hadn't known the regulation to show it."
       "Why didn't you asked me first? How can you know the regulation?"
       I just bowed down my head. Actually, I thought she would enter the class and we show it  in the class but I was wrong. We must meet her in the teacher office and show it  there. I was still confused about something. I asked her.
        "How does method to show it? By oral or to be written??"
        "By oral...!" she answered.
        "Uff, I thought to be written..." I said.
        I was entirely think that the formulas will be written.
        "Actually, you must write he formulas and read it loudly about the name of symbols and you must remember 'JOULE, KILOGRAMS, METERS, CELSIUS........."
       Bell was ringing.
       "OK everybody! I'll wait anyone who wanna show the formulas memorized."
       Oh My God! I hadn't memorized them (Joule, kilograms, m/s, Celsius, second, rad/s and else). So, I wasn't ready. Oh Mam... I'm so sorry I can't show it because I don't know if Joule, kilograms and else are memorized too. :'(   I know I'm like a liar.
