MR. GOTTER

I had a teacher, his full name is Forei Gotter. But, all of my friends was used to calling him Mr. Forgotter. I didn't know yet, why he's called as Mr. Forgotter till the day told me that.
As usuall, one friday morning inside of my class room, Mr Forgotter spread many words about history.It was about world war. He spoke seriously and full of spirits with his unique, glasses was put on his head.
After explaining four a half pages, he sat on his chair and tried to find something on his lovely book.
When I saw him, he looked like found what he was trying to look for. He grabbed something in his bag, but it was nothing. His right hand reached a pocket on his pink cotton shirt. He found nothing, he was still looking for it in his bag again. He's looked so fool.
"What are you looking for sir" I said
"No, just my glasses, I forget where i put it in"
All of my friends were laughing at the time, he's ridiculous appearance so unpredictable.
"It is on your head sir!" One of my friend spoke loudly.
He took it from his head and put it on his eyes.
"oh yeah, thank you" He smiled smoothly and continued his talking
"do and finish your task"

We focussed to our task back. Suddenly he stood up and said
"I'm really Mr Forgotter"
Directly all of human in my class laughed.
