They're always nippy. Mine also hate being petted, they're VERY independent. One loves things that make crinkly sounds (like platic/bags for potato chips) and the other steals every shoe that is out in the open and hides it under a bed or behind the couch. I can also get them to come running if I open or close a door anywhere in the house.
Did you only get one (I assume by what you're writing)?
