It's a psychological thing, there is no real difference between the two, but 6 sound much bigger, that's why vendor write shit like 0,99 dollar rather than 1 . Short guys got it so brutal and height isn't something you can change. I'm very short, I've accepted the fact that my girlfriend is always going to be taller and isn't a problem. But I could never see myself with a girl one foot taller. I mean, what counts is character and cute face and not bone lenght, but there is a point when height difference just means discomfort. And don't get all these short girls refusing short guys and going to the one way taller. Must to be sexual disphormism or something. But the reality as a very short dude is rough and they dont' make up dumb nickname against women who don't want to date them like men in dresses
