Twice. The first time my brother and I (18 months difference) planned to run away to the big pine tree about 250m down the road where we had built a big treehouse out of the poles leftover from a football match at the oval across from our house. I was about 9, my brother was about 7. We planned a nightime exit.Everything was going according to plan until one of the jars of honey we had pinched from our large backyard shed (full of books and preserves etc) leaked all over my sleeping younger brother's head. We started whispering furiously and my dad woke up and discovered us.
The second time I was about twelve. I had a huge row with my mum over something I can't remember now. I took off on my bike and rode down into a nearby valley .. It was about a two hour long bike ride. A farmer who knew my parents saw me and waved. I rode on hoping he'd think he was mistaken. Well, anyway, he rang my dad and asked if he knew that I was down in the valley by myself. Dad said no and he told my dad he'd pick me up and let me spend the afternoon at the farm. By then I was getting pretty tired and started to regret the whole thing as I'd have to ride up a rather steep hill to the ridge if I wanted to go home. I stopped my bike at a river ford and pondered what to do. Then Bill showed up, gave me a friendly grin and asked if I was running away. He listened very sympathetically to my tale of woe with my mum and said I could come back to the farm and have something to eat if I liked before going on. I agreed to that and his wife had put out some scones, jam and cream . They let me muck around with the horses, I helped clean out the chicken coop, picked some blackberries, fed the pigs, he showed me a new Arab they'd recently bought ( whom they named 'Yasser'), ate more scones and then they said at about six "maybe you should let your dad know now". During none of that time had they let on that they'd already contacted my parents. Dad came and picked me up and they all had a chuckle ( but good naturedly).
My relationship with my dad is still good. It's a bit more mixed with my mum as she has always been a bit volatile and used to fly off the handle easily.
