Anyone up to talk? Be friends? Is what you meant to say :)
Answer: Grandpa: 60 Granddaughter: 6
Explanation: When I first saw this, I noticed you can not get one solid whole number with a number like 54, so I rounded it up to 60, because 10 percent of 60 is 6. It IS possible for someone to be 5.4, but with age, not a lot of people care to go down to the decimal point. I then checked the other part. 60 IS 54 years more than 6, so 60 is correct.
But, in an even bigger sense, we cannot dedicate this ground. The men we honor, living and dead, who have struggled, have consecrated it, far above low power to add or detract.
