The present perfect serves in different aspects and conveys different nuances two of which are these:
1) An action with a result in the present.
I have bought a new sweater. = I have a sweater now.
2) A collection of life experiences
I have seen this movie. = I have the experience of watching this movie.
However, I think there can be a clash between the two. For example, if I say.
a) I have lost my keys.
Can it mean both 1 and 2?
I have lost my keys. = I don't have them now.
I have lost my keys. = I know what it feels like to lose keys. I have had it happen to me.
Do you think this confusion is technically possible. If yes, how can we tell one from the other?
For example,
- Did you know that Joe has lost his keys today?
- I have lost mine as well... it's not a big deal...
Does the person say that he doesn't have his key as well or that he has lost them as past of his life experience but now he has them?
