You HAVE to laugh at them!.... either that or the criminal stupity and needless suffering will simply overwhelm you!
The very thought of not getting to spend time with my grand daughter because I didn't agree 100% with my daughter on some stupid issue would put me in an institution!
Perhaps your friend could use the law to her benefit (the Apostle Paul did with his Roman citizenship) She could easily file a suit for Grand-parental visitation rights.... I'd love to hear the son's defense argument for why she's being denied this relationship. My parents had to resort to this after my brother's death. My mom was DA'd but my dad was in good standing. It wasn't until the case got heated that we decided that there would be too much trauma on the grankids to pursue it any farther .....so we dropped the suit.
