-
Choose an appropriate theme or tone for your anniversary message. The tone of your anniversary wishes to your sister and brother-in-law can feel sentimental or lighthearted. They can be funny, focus on a milestone, appreciative, or inspirational. Choosing a theme can help your message have a specific focus, from married life to romantic love or your relationship with your sister and brother-in-law.[19]- A sentimental tone celebrates the romance between the couple, along with their relationship.
- A funny anniversary writing style likely includes a joke or speaks about the more humorous parts of being married.
- Inspirational-themed wishes let the couple know how much their love impresses you.
-
Personalize your wishes with a shared memory. Choose a meaningful memory, story, or anecdote that will touch the couple deeply. It’s important to share a story that reflects not only your relationship with your sister but also touches on how much you appreciate your brother-in-law. Speak authentically, and limit your personalized memories to a few lines, unless you have room to write more.[20]- Inside jokes, childhood nicknames, and short stories make great additions to your warmhearted anniversary messages.
-
Include humor when appropriate. It all depends on your relationship with your sister and brother-in-law. If you feel comfortable telling jokes or poking fun at married life with them, it’s perfectly fine to include humor in your greeting; if you know they’re a little sensitive, it might be best to stick to a more sentimental, lighthearted anniversary note.[21] -
End your anniversary greeting warmly. If you’re writing an anniversary card to your sister and brother-in-law, close with ending salutations like “Love,” “Warmly,” “Your Sister,” or “With Love.” You can also include “xoxo’s” next to your name or sign the card “With love from the family.”[22]- When sending anniversary wishes on social media, you don’t need formal opening and closing lines; simply write a short greeting that includes a few fun emojis to express your love and appreciation for your sister and brother-in-law.
