As a private DJ I do all kinds of event, my favorite have to do with the elderly.  Especially with the nursing home and assisted livings parties.  They hunger for something fun, and they really do dance like if nobody is watching :).  Why can't we always just let loose and have a good time, without caring about what other people think.?  While all people do like to have a good time, it seems the elderly and youth really just know how to have a good time with all their heart.  I wish everybody was like that!
