I'd like to object to this hopefully unintentional suggestion that failing to understand it means you're a terrible person. I don't think I'm a terrible person. My kids are healthy, mostly happy, seem to be well adjusted. I support their physical needs, do my best to support their emotional needs. I read to them, changed their diapers, taught them how to ride a bicycle, help them with their homework, kiss them goodnight. But I still don't understand. I know most parents have this whatever it is, but I'm still wondering.
