That might be the case, I always had to call my mom when I arrived and departed from a friend's house when I was Lizzie's age. And that was decades ago, when things seemed safer.
I'm afraid the point I was trying to make in my original post is being overlooked. It wasn't whether or not Lizzie called, or whom she called. My point was that obviously Lizzie rode her bike further than one block from her house. And she did it often enough that her parents had implemented rules for her to follow when she did so.
Therefore, if she did ride further than a block from home, where did she go, who did she visit, what route did she take, who did she come into contact with? This isn't anything I've seen addressed before by LE or in MSM, but to me that would be important information. Because while she was out of her parents' watchful eyes, she could have biked past some sicko's house often enough to catch his attention.
After all, we don't know if it was Lizzie, Lyric or both who were targeted by the perp. Many have speculated about Lyric and her possible exposure to the unsavory acquaintances of one or both of her parents. But couldn't it be just as likely that Lizzie was spotted biking alone by some pedophile?
Again, just throwing out some ideas. And jumping off your post, not necessarily directing these comments to you specifically.
