It kinda felt like she holds some sort of grudge? Dont like her at all, but sometimes I get the feeling she gets constantly hurt by Alfie's stupid attitudes. They certainly deserve each other, but I don't know, it seemed like the "I paid for Nala" was uncalled for, because that's a tit argument for getting a pet if you breakup with someone.
Also, the constant interrupting her... Not sure if she got upset, but I would have. It is very exhausting when you're trying to talk to someone and they're purposely ignoring you. And I got the feeling he does that. A lot.
