There is a kid that tried to steal my purse and I plan on being rude with him.
What happened after he tried to steal your purse?
He ruined the experience for me, he should be ashamed of his actions and I'm not going to allow him to ruin my day
If he tried to steal your purse then it's understandable that you don't want to be friendly with him. He should be punished by his parents.
That's a good idea, I should ask his mother make him face the consequences of his actions.
Speaking with the parents is the best thing you could do in the situation. That way they can provide the discipline needed so he does not do something like this again.
