I'd like to know more about the visit with his family that morning. Why was he so against having lunch with them? What's off-putting about going out to lunch on a Monday afternoon, especially as nice of a day as that one was with warm, easy temps?
Sure, it's possible lunch with family bored him, but seems like something a person would go along with rather than skip lunch and drink beer instead. Was he always uncooperative with them?
Was there a specific reason both he and his sibling met with Mom that morning? Was there a conversation that upset him?
And how do you go from visiting with family in the morning to murder in the afternoon....and then go on with life.
We don't know that much about RA, but what little we do know seems so pathetic, self-centered, and empty.
