"arguing" is fun. It does actually accomplish things, likes boris said, she fights with her boyfriend all the time, but after they fight they don't have the pent up anger anymore and they go back to being happy. I like arguing because it resolves a lot of issues and also gives you a better understanding towards other's emotions. I actually think it's quite useful. Oh and you said no one ever wins an argument, but that isn't necessarily true, you can win argument in debate class. ?
I argue with my clothes when deciding which garment to purchase. Like once I couldn't decide between the gray pants or the blue, xD so I had a debate on which one was better, make the pants have their own personality. Quite amusing, yes.
