What Sahara Said

I was reading Sahara the Three Billy Goats Gruff tonight and we'd got to the part where the littlest billy goat gruff was telling the troll to wait for his brother and she said
"That's really mean! Does he want his brother to get eaten?"
"You know what's meaner? That the biggest billy goat gruff let his little brothers go first even though he probably knew he could take the troll. Why would he assume the troll would just let the littler ones go because there's apparently a bigger goat coming instead of just eating them all? He could have just gone first instead of risking his little brothers."
"...that's stupid. Then it would be a really short story".
