70th birthday poems: Seventieth is a unique milestone birthday because it signifies the beginning of life’s sunset period. This is when old age starts to show its true colors. So whether it is your grandpa, grandmother, uncle, aunt, mom or dad – write a sweet quote on their seventieth birthday greeting card. Show them that no matter how old they get, your emotional support and love will always be there. Oldies can sometimes be annoying but their silly idiosyncrasies often make the cute and funny memories. Spend some time with them and cherish each and every moment of togetherness to the fullest. After all, life is fickle, especially after seventy.
