Maseeh while watching the Obama speech:"Did Donald Trump say I am sorry?"
"No...he has not said I am sorry yet."
"Why?"
"I don't know."
A few minutes later I explain to him that Obama is asking people not to vote for Trump because he is mean and bullies people. And then he asked :"Did Donald Trump get sad?" And I pause....."yes I think he gets upset when he hears this." 
"I think so too....maybe we should go talk to him and tell him he should not say mean things."
And this is how I learn a lesson in empathy from my 4 year old....
