Mention a specific memory — the time she covered for you, the advice that saved you, or the way she makes you laugh until it hurts. You can be sentimental or silly, as long as you are sincere. A handwritten note tucked somewhere she will find it, a surprise text on an ordinary day, or a heartfelt toast at a family gathering will all mean the world to her. She already knows you love her; tell her you are grateful too.
