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!
We used to fight, squabble, and argue, we would laugh together and make fun of each other. Actually, come to think about it, not a lot has changed really, little sis!
As your elder sibling, it’s my duty to boss you around and act as though you’re always bothering me but seeing as today is your special day I’ll give you a break!
