The phrase “How did I not know about this? Learned something new!” is usually used as a caption for a surprising discovery, but it does not identify what the discovery is. Without the actual tip, trick, or fact, there is no specific detail to explain.
If you mean a viral post that uses this caption, please share:
- the full text of the post, or
- a photo/screenshot, or
- the topic (cleaning, cooking, gardening, health, technology, etc.)
and I can explain the details, whether it works, and any important cautions.
