It must be so nice not ever having to worry about your age because at least you’ll always be younger than me! That’s possibly the best gift I could ever give to you!
You might be older than me but you certainly don’t look it! It seems as though you were blessed with the good genes in the family, sis! Happy birthday!
There is no gift in the world more precious than a beautiful and unique sister like you, and there is no gift good enough for someone as incredible as you.
That’s exactly why I didn’t get you anything this year, sis! Happy birthday!
Having a younger sibling like me is tough competition and while you may not have won the title of favorite child when we were growing up, you’ll always hold the prestigious position of fav sister to me!
