Any way, to get technical, cuffing of the arms is way a good way of saying ” i like and respect you, and we are just boo thang, dating, or even good friends”.
Holding hands is sign of a deeper respect or relationship. Sadly, I rarely see this. I see more couples walking with the women on the cell texting, and the brothers pulling up their pants.
I think there has been a decline in overall GQ (gentlemen quality). To see other guys get of the car, walk to a building and wait on their girl who is still in the car is a big NO NO, but no one in the situation sees a problem with it. I guess I am one of a few people out there that see this as a sign that there is no respect in the relationship or self-respect.
Holding hands is a cool thing. Don't rush it. Want for it.
