Looking for keys that were lost in the park

1. It’s like looking for a needle in a haystack.
2. Maybe we’ve been looking in the wrong place.
3. Maybe we’re barking up the wrong tree.
4. I think we’re wasting our time.
5. Sometimes you just have to know when to call it quits.
6. Let’s just call the whole thing off.
7. After all this effort, I no longer know if I’m coming or going.
8. I’m totally tuckered out.
9. I think it’s a lost cause.
10. Let’s do something else for a while and just keep my eyes open for it.
