Frequently Asked Questions

How many captions are in this collection?

There are 250 original lines, all written for this article. There are no famous quotes here, because a caption for your own brother works best in your own words, not borrowed ones.

What is a good short birthday caption for my brother I can post on his story?

Pick one from the short section, such as “Bro, cake, candles, done.” or “Happy birthday, bro. Short line, big love, you today.” Short lines work best posted as they are, without a long explanation attached.

Say the distance out loud, then send the love across it. The long-distance section has 25 lines for that, including “Happy birthday, bro. I counted the miles, then I counted your candles instead.” A video call once the candles are lit pairs well with a short caption at bedtime.
