If you could call anyone, dead or alive?

I can call anyone, dead or alive?  The past is already written, and changing any one thing in the past may change the present in unforeseeable ways, so that’s out.  No telling Lincoln not to go to the theater, or calling the cops in Dallas to tell them about the gunman (gunmen?) before Kennedy got there in ’63.  The call I make would have to be for my enjoyment or education, if it is made to a person from the past.
What about the present then?  Can I call Obama and tell him America is not happy with him, that he is not representing the will of the majority?  How about my self-serving Congressman or Senator?  Would they even listen?  Would it make a difference?  Naw, I’d just be wasting the call.  Politicians only care about getting more power and money for themselves, and pushing a party agenda.  They don’t care about the will of the majority, including me.
Who would I call then?  Assuming I can speak to the deceased, I would call my Father-in-Law, Milt.   He has been gone a few years now, and I still think about him and miss him every day.  For nearly 20 years, we used to sit and talk often, sometimes for hours at a time, about anything that came up that day.  Milt could tell a story (Man, could Milt tell a story), and he had a never-ending supply of them.  I never got tired of talking to him. 
If the call is to be placed to the living, I would not waste it on a politician, or some movie star, or to call some billionaire and ask for money.  Nope, I would call my Mom and Dad’s house, and shoot the bull with whoever answers the phone.  Between the work schedule, the kids, the grandkids, and our rundown old 1860’s house, I simply do not make the time I should to call my parents.  We could talk about anything, wouldn’t matter much.  Mom can catch me up on the family info, who is sick, who is mad at who, etc.  Dad can start a discussion about politics.  It's always fun to disagree with my Dad about Politics.  I think he enjoys it too. Either call would be well spent. I can't think of any call that would mean more to me than one of those.
