My son ( the math genius) has been telling my wife and me for years that one day he’ll be so rich that he’ll have rooms in his house just for storing his shoes ( separate rooms for left and right by the way).  So for Christmas this year, he let us know that he’ll take care of us in our old age by awarding each of us this legally binding certificate…

P.S.  I guess he was feeling generous since he moved us up to the right sandal room…
