Half of the people in my church congregation are huggers, the other are hand shakers. The hand shakers usually get their hand out real fast, and I take it. The huggers will spread their arms apart ready to receive you. If I don't really know I start out offering my hand, and sometimes that person will take my hand and then start to wrap their other arm around me, to which I respond by dropping the hand and putting both my arms around. This is Oklahoma, and kissing is usually done only with relatives or intimate relationships.
