MY DADS NAME IS JOHNATHAN LAURANCE GARDNER , SORRY MIGHT NOT BE RIGHT SPELLING OF NAME. MY PARENTS SEPARATED AND WE WERE PUT UP FOR ADOPTION AND MY MOM SAID THAT OUR DAD WAS IN THE AIR FORCE WORKING ON PLANES AND THAT SHE LIVED WITH HIS PARENTS AND FAMILY FOR A WHILE WHEN HE WAS GONE . PLEASE IF ANY ONE CAN HELP THAT WOULD BE WONDERFUL, ALL I WANT IS TO OPEN OR CLOSE THIS CHAPTER IN MY LIFE SO I CAN MOVE ON A STOP WORRYING!
