Eg: We go with her when she wants to feed the ducks. On the way home we need to pass by the grocery to buy stuff for the house. She would whine and complain that she doesn't want to do that...
And that we should just bring her home. Or that she shouldn't play with the dogs while they're eating, she'd argue... so... we cancelled one of her activities and ice cream.
Negative punishment is when you take something away, positive is when you add or do something such as spanking or lecturing or additional chores or tasks
