@popmol it really depends on who you feel is nemesis worthy. But for me anyway, I drop people from my life if I have to and if for any reason they continue to be around me either intentionally or just by mutual social association i make a point of fucking with them forever.
@Flenflyys ooh yeah if you split and they agree but they keep going busybodying in your sphere of influence (unless you are in the same friendgroup) they should get a reasonable response back!
