I read this story based on an earlier recommendation of the book of stories by Elizabeth Berg with this title. I didn't really find it humorous then, so I tried to reread it today, but the link wasn't to the complete story. It was enough to remind me of the story.
I think my lack of appreciation of the story is based on the fact that all my life I have been slender. Genes, and a family diet that always was more fruits and vegetables than heavy foods are responsible, not will power. When you can eat anything you want, then it's not so important.
My favorite calorie-filled snack is cashews or dark chocolate.
I do know a few women like Sigrid. I enjoy their humor and their confidence.
