Never take yourself so seriously that you aren't willing to do things that will make your kids happy even if you look and feel like a complete (you know what) in the process.
None of us knows how many days we're allowed so make 'em count! Besides, life is too short not to have fun, be silly, and acta fool. (Not all the time because that just draws the wrong kind of attention - the kind requiring long white coats.)
Btw, I figure my kids will most likely need therapy for something in the future so it might as well be because I put my book, Nook, Kindle, iPhone, laptop, etc. down and made silly dance videos with them. (I'm kidding about the therapy part...I think.)
