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!
I’m wishing a heartfelt happy birthday to my dear brother today as he turns another year older and more wonderful than ever. Best wishes to you from your adoring sister.
I was going to make a joke about how you’re getting older, but that immediately backfires as I’m always going to be older than you! At least we can make fun of each other as we grow old together!
