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!
How is it that you’re my elder sister and even though you’re turning another year older today, you simply never seem to age?! You’re making me look bad, sis!
I hope that I too will follow in your footsteps and just stop ageing at a certain point as well!
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!
Being the elder sister and having to look out for me can’t have been easy when we were growing up, especially as I didn’t try and make it any easier! You must have had the patience of a saint back then!
