Me and my friend always come up with crazy stories about wanting to kill our teacher we are joking but i laugh my ass off and they are fun stories and we wouldnt actually do it but part of me wants too. i would never do it but its fun to talk about it. is this normal?
But... make sure you're not the only that's just joking. Don't get dragged into a very bad situation if your friend starts taking things seriously. And if you ever think you might be serious, then you need to talk to someone right away.
