Girls who often like to go bouncing should like to seek excitement, go inside to relax themselves and forget themselves.
The girls in the disco, from the old man's point of view, it must be a bad girl or do not learn good girls, from the young man's point of view can be said to be fashionable, exciting. Inside the contact between men and women, to friction, to find excitement.
On the other hand, most of them are single or just the kind of girls who don't learn well in order to seek food and drink or money to go there. I don't think a girl from a decent life or family would go there.
I can only advise you to stay away from such a crowd so as not to delay yourself and waste your time and youth.
Personal advice is for reference only, I hope my answer can help you, hope to adopt thank you!
