Can I take candy from a little kid?
Why would you take candy from a child?
Because I like to watch him cry
You shouldn't mess with people just to see them suffer. People will start to think you're cruel and a psychopath. They'll want to avoid you in the future.
Well I like candy and they should share.
Are you really stooping so low as to take a babies candy? You should find your own candy if you are craving it so much. No one is required to share if they don't feel like doing so.
