Because I didn't.
When I was young (so young that I don't remember it) I wouldn't eat strawberries because they were red.
And then my dad was like "Eat the f@ckin' strawberries!".
And I ate them.
So now I like them.
What I'm saying is, try to try new stuff.
What I'm saying is, plain old rock-paper-scissors is boring, you'd better try playing rock-fire-scissors-snake-human-tree-wolf-sponge-paper-air-water-dragon-devil-lightning-gun.
Here's how to.
