I'm gonna plagiarize my graduation speech, but tweak things so it's unnoticeable.
It's just a speech, it's not for a grade. Why not write your own?
I cannot do things well on my own.
It'll be the last thing you have to do for school. Why not just take the time to write your own instead of essentially lying? That's untrustworthy behavior.
I'm cool with that, I really don't care about other people's opinions or trust.
You shouldn't be so nonchalant about cheating. Make the effort and write your own material.
