So a common question girls ask their boyfriends (I've heard it referenced a bunch of times) is "if your mother and I fell into a river, who would you save first?" Imagine the kind of idiot someone has to be to honestly ask that question. Now imagine the kind of idiot you have to be to answer that question with something other than a slap.
This is a convo I had with a former co-worker, she had made some some like "if your mother falls in the river, throw me in too" because it's so hot.
My response was that fortunately my girlfriend has never (and would never) ask such an idiotic question.
On a related note, if you've been in China you've probably scene someone's girlfriend acting like a spoiled brat with her boyfriend-whining like a child, hitting his arm, stomping her feet etc. Some may not know that is is an established part of Chinese romantic culture, and (apparently) Chinese men often find it quite alluring. It's called Sajiao, and you can read more about it
here. For me, the second time I met my gf it came up (or I worked it into conversation), I think we saw an example of it at the bar. I made very clear that I didn't find it cute-on the contrary it was a dealbreaker. I'm not sure if that influenced her behavior, she's independent-minded enough that she probably never did it anyway.
