I think it should be on the day you turn 18 you get 1 wish. But it has to be that uber realistic genie like "i wish for a million bucks!" a million bucks (deer) appear. And you can't ask for more wishes, but you can ask for time to reset or you could wish to live forever type of ordeal.
This is where I write a well constructed response. But, you know, my friend just tried to show me a picture of a six-dimensional object, so I'm just done with life in general. This topic has one opinion, so I'm going to just change that real quick... Fuck you SilverWoof
Imagine what people would do, especially if the wishes had no bounds, people could be doing stuff from resurrecting Hitler to creating a nuke capable of destroying the world as we know it. That could be just the tip of the iceberg, people could wish for inter-dimensional travel, the universe might self-implode. As much as I would love to elaborate more, this topic (and answer) is a joke on its own. Lol have a nice day
