Elementary, My Dear Barista

WHAT POSSESSES PEOPLE TO START A CONVERSATION about one topic over another? I mention this because this morning while I was trying to inhale my coffee one of the Usual Suspects started waxing nostalgic about her years in elementary school. After an unspecified number of decades why did this come to mind? I remember my years in elementary school, but I feel no need to bring it up for discussion.

I do admit that there are worse topics for discussion at that early hour. Honestly I also do not feel like listening to someone give me the details of their latest hospitalization for that nagging parasitic problem…At least not if I am eating at the time.
