I'm not saying that there's anything wrong with what you've been saying, Roxy. My issue is how you've been saying it. Not stopping to consider anyone else's points of views, not even accepting when someone apologizes. Blowing up and turning everything around. That's the mark of being a genuine bitch about it.
Below, for example. My Mum has apologized several times that I've seen, both to you and to the girls. But you've been nothing but rude to her in exchange. No, I'm still not saying her words were in the right either, but she's apologized and you treat her like she's nothing. I know she's not perfect, but you're not perfect either. Not with this attitude.
And I hate to blow up like this, I do. I've never liked genuine confrontation, I've always tried to be the pretty nice bloke. But... I just don't understand why you're being so mean.
