A woman passing by us looked over at him, alarm registering on her face. She looked at me as though for an answer. I didn’t know what to say.

It’s not hard to see where the fear is coming from. My son’s father is a runner, nearly vegan, and very fit, bordering (in my opinion) on manorexic. He has been extremely controlled and careful with his eating for all 14 years I’ve known the man, because of a family history of diabetes that he has reasonably done his best to avoid.
