Give knowledge of yourself, what do like, don't like, want, believe, think, plan.<p>Notice that another person who <i>stands off</i> doesn't give such knowledge.<p>(2) Caring. Care about the other person, monitor their life, reach out to help them.<p>Notice how common it is for others just to give you their middle finger.<p>(3) Respect. Grant credibility, honor, pride, praise.<p>Notice how others may give you contempt and insults, try to manipulate, take advantage.<p>(4) Responsiveness. Monitor what they do, listen to what they say, use those two to think about their lives, and do respond appropriately.<p>Notice how others can not respond, just ignore, turn away.<p>(5) Affection. It's basic, involves physical contact, especially with facial contact, hand holding, hugging, and apparently is universal at least in all mammels.<p>Notice how others avoid physical contact.<p>Uh, as a teen boy dating a teen girls, mostly interested in (1)--(5) or just some anatomy lessons?
