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!
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!
People say that you get more beautiful with age, but surely they mean you become more beautiful on the inside because the cracks are certainly starting to show on the outside!
I’m just kidding with you, sis! I hope you have a wonderful birthday today!
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!
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 fabulous sister who is so generous and forgiving, and quite simply the nicest person I know!
Your big heart and kind nature are actually very lucky for me, as I may have forgotten a small but important detail this year: to get you a birthday gift!
