I just stole your idea.

theft != crime

As much I hate to admit it, I have no proof that it was infact my idea. So there’s not a damn thing I can do about it :(

But, if I had in fact patented a practical implementation of my abstract idea, or my idea itself was about a practical implementation of a thing and it was patented, and you stole it, we’d have loads of fun doing a tango dance at the local courthouse. Assuming of course that I could afford the lawyer to dance on my behalf, considering my terrible dancing skills.

> I just stole your idea.

i feel like this may be a category error; it's not clear that "idea" is something which can "be stolen".

at least not in a way that seems similar to (for example) having your car stolen.

subtlety, a lost, and now down-voted, art.
