Bowled Over..

  I was recently privileged have this information brought to my attention... My daughter's father, who can't seem to find the time to get a job - did find time to join a bowling league,  recently got kicked out of the bowling alley because he threw a bowling ball at a fellow teammate for "making fun of him and embarrassing him."  In what world does this happen?  Apparently, he the teammate was hurt and bruised severely in the incident - however, no charges were filed (of course).   If a grown man can cause such rage -  imagine what a two year old can do!  My daughter is my life, and this is extremely upsetting that my daughter could be subjected to this... My question is - How can I incorporate this into my case against him?  Am I just expected to sit around and hope that my daughter never experiences this or worse?
