Sister birthday wishes depend a lot on who's older — what you'd say to a didi who's looked out for you your whole life is different from what you'd tease a chotti behen with. This page splits it that way: wishes for an elder sister, wishes for a younger sister, funny lines when teasing is the whole point, and emotional wishes for when the day calls for something real. Everything below is free to copy, no account needed. Want to turn any line into a photo banner instead of plain text? Scroll down to see how.
