Arrested?

     I got an e-mail from my youngest daughter in Canada. She writes that one of her group was kept under restraint by police at immigration. She was allegedly considered to be bringing drugs into Canada.  A drug detecting dog caught the smell of drugs from her backpack. She seemed to be questioned for about one hour. After one hour's investigation she was released. She had brought rice balls and soft-boiled eggs in her backpack. The drug detecting dog seemed to point out the smell of it.
     By the way, how did my youngest daughter feel about this incident? She loves dogs and wants to become a vet in the future. She wrote to me, "Dogs are great!" I shared laugh with my wife.
