Thou art banned, for I know thou art speaking exclusively to Zella, but want to throw in my two cents:
I honestly don't know what my least favorite childhood memory would be, or my favorite, for that matter, because there are so many good and bad ones. One very bad memory, however, was when I was going to give a mean trick letter to someone at church that I didn't like. I don't think I really thought through the full implications and cruelty of what I was going to do, for I was only eight, but I got in serious trouble. Thankfully, the letter was never delivered. I shredded it up and flushed it down the toilet.
Another dreadful memory was that I wrote some awful short stories where dreadful, embarrassing, and sometimes hilarious things happened to people I knew in real life. I thought they were great, and shared them with my friend, and she loved them too. Then her parents read them. I never actually got in trouble, but... it was traumatic nonetheless.
