Am i wrong???????

You are right and wrong. Personally I wouldn't want to help out either with a toddler behaving like that, it's a train wreck waiting to happen as well as nerve wrecking. However you didn't mention if you are the only transportation for your aunt. If you are then it is wrong to avoid the situation just becuase of a spoiled brat. If your aunt hasn't had children it may not be a bad idea to ask if she'd like any advice in taming the little imp. It needs to be done soon or she's gonna be in big trouble fast.
