I put our dogs left over can food in a dish and into the fridge. In the morning at breakfast my mom asked what happened to the dog food Dave put in the fridge? My Dad said Dog food? I thought it was canned hash and ate it fried with my eggs. I was laughing and Dad said what's so funny it was very good." +
" Then all 5 of our family members bought Dad canned dog food for his birthday as a joke. Was a funny and happy birthday for Dad. Now he has been gone many years but I will always remember this time and the Love he had for his kids and wife.\n" +
"Another funny thing Dad did. We all were taking a local bus home from a movie night as a family. A lady said hello to my Dad and he said do I know you. She said yes I work as a nurse where you are the maintenance man. Oh he said (she was not in her nurses outfit), so he said I did not recognize you with clothes on. The look on our Mom's face made us laugh for a long time. Dad never understood what he said that was so funny.\n" +
"When I turned 15 I was allowed to spend vacation time by my grandmother. She was very tidy, and I would not understand why she would keep this big aluminum ladle with all kind of bumps and dents on it. When I asked her why , she said to me, \"This ladle is your family's history. This dent here was made by your father\'s head, this one comes from your aunt C… this one here from your aunt J…. , like I said, it is your family\'s history, which is why I keep it\n" +
"My father and his friends had gone fishing and brought back so much mullet fish that they could feed the whole village, which was rather unusual, mullet fish being hard to catch. Nazi soldiers had just been defeated and sent back as prisoners of war. They had destroyed as many weapons as they could, but some had been forgotten in hideouts. My father (a teenager at the time) and his friends had found a highly efficient and fast way to catch fish\n" +
"They would attach a rope to the handle of hand grenades, trigger them, spin them around their head and throw them in the harbor where the explosion would bring whole schools of fish to the surface….\n" +
"My father did just that, on this day and when he reached my grandmother's house; with a big smile on his face, he had a big surprise: Whahack…. The ladle crashed on his head……\nIt was at a time before internet and even before phone lines were installed, but at a time when any news about wrongdoing would travel at the speed of sound……\nHe learned the lesson the hard way…It was the last time he went fishing with hand grenades\n" +
"To be honest, I secretly admit that I am not a good father, seldom do I take great interest in playing games or reading fairy tales to my children. Not once did I accompany my children to those extra classes which are aimed at developing childrens' interests. On the National holiday in 2003,my wife and I planned to take our daughter to visit the zoo. We did enjoy ourselves at first, watching all kinds of rare animals, feeding bananas to monkeys," +
" fishing in a clear small pond. I was a bit tired, though, by my daughter's endless questions concerning the names and characteristic of the caged animals. But everything changed when we came to see the bears. There were fences all around, my daughter stood beside the fence, holding the metal rails. To see the bears more clearly, she mysteriously reached her head inside metal rails. The most frightening thing of all was that she could not get her head" +
" out of the metal rails no matter how hard she tried. she cried and screamed , attracting almost all other visitors. Everyone was watching and offering advice, my daughter became the centre of attention. I rushed to the animal keepers for help. Two of them arrived on the scene with a ladder. They climbed over the fence, led the bears into the cave and finally saved my daughter. Tears in eyes and sweats all over, I thanked them for their timely help. " +
"I was to blame for I failed to watch her closely. A conscientious father could never ignore her child only to amuse himself.";
