“My grandfather had an infallible trick to repair bare spots in the grass with almost no effort. That’s how it works”
But it never actually reveals the trick. It’s a classic clickbait teaser—it promises a simple solution, then cuts off before explaining it.
So if you replied:
“No, really not… I hadn’t the faintest idea!”
that response is perfectly natural. It means:
“No, I honestly have no idea what the trick is!”
or
“No, I genuinely didn’t know (because the image never says).”
If your goal is to respond to the post in idiomatic English, you could also say:
- “No, not at all—I hadn’t the faintest idea!” (more emphatic)
- “Nope, I have absolutely no idea!” (more conversational)
- “The picture never tells us, so I haven’t the faintest idea!” (specifically referring to the image)
The joke is that the post leaves you hanging, so saying “I hadn’t the faintest idea!” fits the situation well.
