People who believe what they want to believe despite the proof before them, one can never win and the option I now choose for my own sanity is to rise above these challenges before me and not dwell on what I can't change 
 
No point in arguing with someone whom has a closed mind and just seems incapable of seeing the facts before them!  
I no longer get upset by this,  I just pity  their way of life especially when they wonder why my boy's have no time for them as they refuse to visit him that is something else I have accepted although very sad nothing I can do about it, I can only suggest as I do on many occasions that they come with me despite knowing what the answer will be and that is a polite no Mum.
