A childhood belief about getting older

I used to believe that when you "became" a grown-up (a huge, dramatic event in which you went to bed as a kid, and then magically, when you woke up, you'd turn into an adult, complete with Disney-esque fairy dust, lol), you'd automatically know everything, and be perfect. So, if my parents got angry with me when I was a kid, it was just because they were impatient that I had yet to undergo the "amazing transformation" that they had, and become perfect like them. Over time, however, I figured out the truth, by watching my parents screw up from time to time, like the time my mom knocked the sugar bowl on the floor and yelled "Damn it!!!" thus teaching me my first psuedo-swear word at the age of three. Or the time my dad built me an intricately designed tree house when I was four, complete with stairs, a porch, and three windows, that he said required trigonometry to build.....but he stupidly measured the door EXACTLY to my four-year-old height, not taking into consideration the fact that I would GROW. Or the time my dad decided to make a "golf course" in the backyard, so me and my brother could practice with our Fisher-Price golf clubs, and he used soup cans as the golf holes, which worked great until the first time it rained, and they filled up with rain and leaves and rust......or the time my dad was teaching my brother to ride a bike, but he neglected to teach him how to stop, until he rode his bike into the garage door and cut his lip and had to get stitches and subsist on Carnation Instant Breakfast for a few days. I have more stories, but I can't really think of any more off the top of my head right now, lol.
