Sunday night dance at century ballroom

After choir practice on Sunday, I went to century ballroom for the live music dance. It was the stealing apples band from Oregon.  Salem or Eugene I am not sure.  The band played a lot of various tempos of music.  There were a lot of good dancers who wanted to dance with new people.  I have noticed that the people who take classes where they practice in teams or work in choreography together are more inclined to dance with those same people.  On this night there were a lot of people, so staying with a group to dance was not so noticeable to those people not in a group. I am not a member of a group.  But I am actually in the group without a membership.  I like that.  I also think it is interesting that people in dancing make a decision not to dance with someone. There are people who have never danced with me, and who have turned me down when I had asked.  Usually I don't ask more than twice on two different occasions, before I decide that they are a person I will not ask to dance again.  I figure if they wanted to dance with me they would ask. Usually they don't ever ask again.  After a while they form a group of people who I name, those people who don't dance with me.  The membership of this group is based upon one or two occasions where I made an attempt to offer to dance together, and I was dismissed with either them saying, "I am fine" or  after looking me up and down, "no". Or "no thank you". "I need a drink if water" and they walk away.  All these are fine with me.  I don't want to dance with a pery who does not want to dance with me.  I can have social interactions with this group, saying hello or good bye, but we don't dance.  I wonder if this is a healthy way to loose at this.  I think it is.   I am not imposing myself on other, and I am not bothered by the group of people who don't dance with me.  It is annoying sometimes if I go somewhere and that group makes up most of the attendance.  But, if it is live music I can enjoy the music, and I can watch other people dance. I like observing the interactions between people.
