My father once lied to me when I was 10 and said the dog ran away instead of he died.
His name is Blitz. Our dad brought him home in a 2X2 cardboard box. We looked at him, he looked up at us. He stuck out a tongue in that lopsided grin of his. It was mutual love at first sight. We'd play catch in the garden. Our dad would unfailingly take him out for a walk every day, and one of our favourite childhood past-times was picking the ticks from his fur and squishing them with a delightful pop. He was a member of our family, an ever-willing playmate, and our vigilant guardian.
I spent a month looking for him every day when he went missing. Riding my bicycle everywhere and actually putting myself in danger a few times. I couldn't understand why my parents weren't looking for him too. Why they weren't putting up posters, why we didn't go the police, kennels, anywhere. I felt terrible about my dog being out there, lost, alone, in danger. After a month of this my father finally came clean that Blitz actually died of a car accident. I hated my parents for lying. I hated them so much that the hate overwhelmed the sense of loss. I'm 28 years old. I still remember this like yesterday.
Now when I look back, I know something more about my dad that, the rock that he is, never let on about how much he had been affected by Blitz's death. Only now do I realize why none of Blitz's photos remain, and why he refuses to have another dog to this day. Also I think the death of pets is a way for children to come to an understanding of death. That's important. People they love are going to die over time. Pets dying first is a good way to prepare them for that.
