The title grabs attention. I assume the dialogue is between a mother and child. Children sometimes have bizzare ideas and vivid imaginations, if you were aiming to convey that you did so well.

I'd have written 'a huge smile that showed his front teeth were missing,' it feels more fluent.

The opening lines are good, they create tension and raise questions of who this man is and how he comes to be brawling. His relationship with his brother is plausible and you convey it well.

There's a lot of truth in this.

I'm not an expert on the technical aspects of poetry, but I agree with your sentiments here.

'A reputation with the locals' not 'in the locals.' That or 'a reputation in the area.'

You evoke the setting and the characters past experiences well. I like the way they think they've debunked the myth only to realise they havn't.

Thete are people like Frank who will twist anything so its in their favour.

If this is autobiographical, remember we are all a mix of strengths and weaknesses, faults and virtues. If things are hard now they may not always be. Other people may have issues they won't admit to. If their lives are perfect now they may have issues in the future. If you've made mistakes there's time to learn from them.

This is nostalgic, plausible and, I suspect, angry under the surface. Similar scenarios are playing out all over the world, including my native U.K. Well done.
