Take some of these cookies I made. Feel free to eat them, share them with your friends, put some chocolate on them, and even share the chocolate cookies with your friends. You have my explicit permission to do any of these things. Just make sure to let folks know that I created the original cookie.

Thanks! Here you go Sally; try out some of these cookies that Joe made.

What? You shared my cookies with Sally? I didn't really want you to share them with her. I'm going to warn everyone about how you stole my cookies and gave them to Sally. That's just straight up theft. I really wouldn't be complaining if you'd put some frosting on them or covered them in chocolate before sharing. That would've been OK.
