What's the answer to this riddle? I'm confused!!!?

[Inexplicably Inexorable.]

I climbed an apple tree where I found apples. I did not pick the apples, nor did I leave the apples. How can you explain this?

I mean, what did they do? Pick up the whole fricken tree and bring it with them?

Whoever climbed the apple tree never left the apple tree.
