Manchild.

 It's been my nickname for Ben for years.    His friends all laugh when they hear it and then I explain its a perfect name.   He's a little bit of a man,  and a little bit of a child.        They all readily agree and say it's perfect!   

  So its "manchild"   

  And then man part hit a bit deeper when I walked into the bathroom to catch this moment.  Dang.  How are we already here?    How?   What the heck.
