Ok, so you're pretty close to your girlfriend. But then there're those habits that you just can't put your head around. For example, you miss her call last night, you'll surely hear it next morning...'why didn't you take my call. I called at 3AM? Seriously!!!
It doesn't matter how the conversation started, you're always at the wrong end. Some girls are just bad at accepting mistakes and guys just have to learn to live with it.
