My daddy doesn’t know how to express love at all. It is my mum that makes everyone happy and calm in our family; while daddy only works day and night, never looking us in the face. But mum makes a wrongdoing list of us for daddy scolding us. She’s a spy!

　　Once, I stole a candy. Daddy asked me to put it back and told the shopkeeper that I would like to carry loads for her. Well, mum told him I was just a child.

　　I broke my leg on the playground. It’s still mum that held me tightly in her warm arms. Daddy drove us right to the emergency room. He was asked to move the car away for that vacant was for ambulance. Daddy got angry, “what do you think of it? A touring car?”

　　On my birthday party, it was, again, my mum that took over the cake for me. My dad? He was busy blowing balloons and setting the table and doing the housework.

　　While looking over our album, friends always ask, “What does your father look like?” God knows. He photos others all the time. So there are many and many photos of my mum and me, pretty and lovely photos.

　　And I still remembered the day when dad taught me riding. I asked him not to let his hands away, but he did the opposite. And I certainly fell onto the ground. I got angry and decided to get on the bike and rode. But he smiled again.

　　Mum wrote every letter to me while I was in college. He, except checks, did write a letter, but extremely short, just a few words, saying, “Without your playing on the lawn, my son, my lawn grows prettier than before.”

　　Every time I phoned, it seemed he wanted to talk, but he would say, “I will get your mum.”

　　On the day of my wedding, mum cried as if we would never meet again, while dad went out with a nasal sound.

　　From very young, I heard him saying, “Where have you been?” “When do you go home?” “Did you get oil for your car?” “No, I don’t agree.” Dad really knows nothing about showing love. Unless... 

Maybe he showed while I didn’t notice, is it?
