That would depend on your meaning of difficult, Amanda. Petulant and difficult could both mean irrationally stubborn. A child could be said to be petulant or difficult if they refuse to eat their veggies, but a rusty gate, while being difficult or stubborn, would not be petulant.

'Difficult' in the sense of a person being difficult to get on with, yes. I'd think grumpy, perhaps spiteful. Collins has irritable.

That helps a lot. Thanks guys!
