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!
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 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 want you to know that I look up to you as if you were my elder sister, cousin. It has nothing to do with age, only the fact that you look so much older than me!
