lol her attitude was harsh at first, you're right. I thought it was downright rude of her not to offer to help - she's a guest in my house and she won't even do the most basic chore to help out? Pull your weight, love, or GTFO! lol (Admittedly, it never bothered me to the extent I didn't want to continue playing.)
To be fair you haven't got very far, though, if she's still got her attitude up. You'll need to progress a little bit to help bring her walls down, don't forget, she's in shock a bit too. Don't worry though, it's not a grind or a chore to get there, it happens naturally as the story develops. It also doesn't take too long.
Honestly, you'll be missing a good game and (so far) an intriguing story, if you don't push past that initial gripe.
