You'll feel better.
I made this web page because I want you to buy a pencil.
After you feel the shot of joy buying the pencil, you'll probably get another shot when a friend notices it.
Maybe you talk about it, enjoy a little conversation, and maybe your friend'll want to buy a fuckin' pencil.
At that point you've given me joy, yourself joy 3-4 times, and your friend gets at least 3 moments.
If they share it with a friend like you did, they get at least 4 moments of joy, and so it fuckin' goes...
