I don't think I really bare a gruge on him but seeing him brought back some bad memories and resentment of his behavior towards me and other people. Not sure if you understand but you never think about some people and don't really care what happens to them but when you see them suddenly a flood of bad memories of the past comes back to haunt you for a moment. Like how he breaks other people's locker to steal their $ or walk past and take other people tools and keep just to let the victim hunt high and low for it just to name afew.
