A sister can be your biggest critic, your loudest cheerleader, and the one person who knows every embarrassing story. That mix is hard to put into words, but a good caption gets close.
Pick the lines that sound like the two of you. Go funny if you tease each other, or soft and sincere if the moment calls for it. A caption doesn’t need to be perfect. It just needs to feel true.
Save this list for your next photo together, and send it to your sister so she can pick her favorite too. After all, she’s probably already waiting for you to tag her. ๐
