Sincerity

My father is a doctor. Today is June 23, 2012. It's The Dragon Boat Festival, a Chinese traditional festival. Everybody can rest at home, except besides my father.
Today, Mom, dad and I are having lunch. At this moment, Dad's mobile phone ranging. I know he has to work.
"What's happened?" I asked my dad.
"Somebody has food poisoning ." dad answered me.
" So you have to go to the hospital? I also want to go.", I said.
"OK! come on !", dad agreed quickly.
Half an hour later, I went to the hospital. We came to the resuscitation room. I saw four men are fighting. Them with had many pipes. Their lips turned purple and their faces were pale.
Soon, a man awake woke up.
"What did you have for breakfast this morning?" my father ask them.
"We ate fried food",The man answered.
Then my dad checked for the treatment of the patient.
I think if the fried man has was sincereity,the customer will was not poisoned. Everyone should has be sincere. sincerity.
