Happy birthday from one wise elder sister to her younger and more beautiful baby sister!
I was trying to think of something funny or witty for your birthday message this year, but all I could think of was silly jokes and cliche anecdotes. I guess you got the gift of being both the younger one and the funny one, sis!
Happy birthday from your better-looking and totally awesome younger sibling!
It can’t have been easy growing up with me, especially as I would get away with anything! Don’t feel bad though, sis, the younger sibling is always the favorite of the family!
Happy birthday to my younger sister who a lot of people think is actually my elder sister!
I’m sure it’s only because you’re so wise and mature that people think you’re older than me anyway, sis! Either that or I just seem super young and immature!
I would tell you not to grow up too quickly and simply cherish the years, but you seem to be doing a pretty good job of that all by yourself, my dear sister!
I’m wishing you a very happy birthday and sending a big kiss!
You’re another year older and more beautiful than ever, little sister! Happy birthday to you!
Just a word of wisdom from your dear elder sister, keep hold of your beauty and cherish it for as long as you can because once you get to my age those good looks won’t stay around for long!
