that's right. once you screw it up with me, I'm always wary with you. Even if you end up befriending me after causing me trouble, I will never not keep an eye out for more potential trouble from you.
And if I encountered someone but left them blocked, it's not that I never forgave them. It's because I can never forget the heck they put me through and would rather not open up my gates to them so they can possibly flood me with more trouble.
