If you can make the concert and not miss anything that involves your kids hell yeah go, you have a life also. I remember when my son was doing all that stuff...Football, Baseball, Hockey, Lacrosse, snowboarding etc., etc. I wouldn't trade all the 5am practices and driving to all the away games and coaching football all those things were awesome !!! He's away at college now. I can honestly say that I miss those days very, very, very much. But, I also had a life in there too and you have to have a balance to stay sane as a parent cause life is usually crazy busy during those years. So if you can go, enjoy it man but, always remember what matters most.
