EJ wants to be a DJ

My  husband and son were looking at dj equipment online yesterday.  I don't know why he is into  becoming a DJ.  He watches these videos on Youtube of how DJ really get into the groove when they are doing their  music.  My son find it very cool  to be a DJ.  The fact that one of my daughter's classmates' Dad is a DJ really encouraged him to become one.  He asked me one time if it's alright to be a DJ and I told him that no matter what he  decided to do when he grows up, we are just here to support him.
