Sherlock

Do you know Sherlock?
Actually,it's Sherlock Holmes,Who was a famous fiction detective.
I have a student whose English name is Sherlock.He doesn't like studying and always
taking a nap on the class.
One day last week, class already began.I stood on the platform,waiting for them to
stop.They ignored me,still on and on and on ...
I was pieced off and shouted at them:"SHUT UP".
And then,my student Sherlock raised his hand and said:"I'm here"!
