Its purely personal choice ?
I've been to events and not danced once and had a great time, been to events and danced as much as I desire and had a great time too.
I am no great dancer by any shakes, but I do what I want as its my own free time.
I don't spend time with any one who might mention more than once that "you havent danced come on" - I left 6th form years ago.................suprise, I am an adult and can and will make my own descions...........
Of course the importance or travelling to me is to hear new sounds, sounds I love and that would normally get me dancing - but I cant "blanket" dance to any old tune that comes on easily.........Its also to experience new places, people and venues...................so a mix. The key is the music though.
Having a good time means different things to different people, so we must celebrate the difference........... :-)
