I'm going to be rude to you!
How do you plan on being rude to me?
I'll ignore your existence.
I haven't done anything wrong to you though?  It's rude to ignore people who haven't wronged you.  I hope you'll reconsider this?
It'll teach you a lesson and maybe you'll see things differently.
Having the mindset of randomly being rude to people is really ignorant. You really consider how this affects people. Continuing down this path will drastically affect your social life.
