“in my book”
Thank heaven your book wont get published !
That’s OK — I’ve been wrong before, and could be very wrong this time. Most folks can’t even admit when they’re wrong, much less apologize.
That being said, I think they spent time at the library to either meet covertly with their son, leave money or a message for him to pick up later, or to give their attorney time to meet with their son before they met with him (keeping the surveillance on them instead of their attorney). But, again, if I’m wrong I’m OK with that because at a minimum they’re acting incredibly strangely as parents (by doing absolutely nothing). They’re involved.
