OK, your neighbor has tagged you as a soft touch, someone she can take advantage of.
Clip that in the bud or it's going to get a lot worse. She'll be asking you for money and cigarettes (if she smokes), to babysit her kids, etc., etc., etc.
And TB is right. I hope you a have a good fence with a locked gate. Keep that kid out or you'll end up with a dead kid and multi-million dollar lawsuit.
