A sister has known you longer than almost anyone, which is exactly what makes her birthday card so hard to write. Everything you draft sounds either too formal or too close to the sappy line already printed inside.
The wishes below are sorted by the moment you need them: heartfelt lines, jokes about her age, short texts, milestone toasts, blessings, long-distance notes and emoji-ready captions.
Pick the tone that sounds like you, then change one detail before you send it. Naming a real memory, a nickname or an inside joke is what turns a borrowed line into something she keeps.
