      I was used to complain about my English teacher                       
for his bad English. I was also tired with his teaching methods,      
it were always slow and boring. However, my attitude towards          
him began to change after one afternoon. It is raining               
heavy and I didn't attend school. Around 5:30 pm I received          
a phone call. "Are you all right?" asked my English teacher in quiet
voice. On hearing her words, I was shocked and my mind was            
flooded with mixed feeling. He was showing his  concern               
for me, though I have not been happy with him! Was he just            
acting and should I smooth away my past misunderstanding of him?
