So Grumpy likes the furball and that's his idea of fun. Then someone who was getting owned in the dogfights sinks Grumpy's funboat, which was probably fun to the boat sinker. Now Grumpy isn't having any fun.
No offense Grumpy, but that sounds like a personal problem brought on by a lack of proper perspective. Inflexibility, failure to look beyond the horizon, inability to see beyond ones private walls, assigning responsibility of ones happiness to others...that's where all the "this isn't fun anymore" attitudes and subsequent whines originate.
Sometimes I wonder how many "old timers" around here are still wearing their polyester leisure suits, cowboy boots and mullets as stuck in the past as some appear to be.
