I asked Rondel to shut the back door this evening because he was letting the bugs in. He did so, then asked me why the bugs wanted to come in. I told him that a lot of bugs are attracted to the light. Being his infinitely curious self, he then asked me why the bugs were attracted to the light – and I had to tell him that I didn't know, that it wasn't something I ever researched or learned about. He paused for a moment, and then said, "Would a book say why bugs like the light? Do we have a book about bugs?" I wasn't sure if we did or not, so he went to look through our science crate to find out (and got distracted and came back with a book about elephants, but still).
