me and my mom grand mother and grandma were building a barn by hand and we (my mom and me) were on the roof fixing it and we were cold and tired and we stoped and my grandfather looked at my mom and asked her is our hamer tiered and she said yes and then he said if i can get up ther i would show u if it was we all laught about it cuz a hamer cant get tired. 

one time he told me that if me and my brother went out side and put are heads to the grass and listen that we could hear the grass grow so we belived him and done it why we did i still dont know till this day.
