When I first joined this site I rallied against some of the old-timers who would gruffly say "you're wrong" etc. I thought all answers should be allowed to stand and judged on their merits.
Now I'm getting a bit older, have been around on this site a bit longer, I'm finding myself being dismissive and gruff, and that's beginning to surprise me because I'm generally quite helpful; at least I thought I was.
This question may be closed for being off-topic. But if it isn't, I'm curious to hear what others think about changes in their own behaviour as they become more experienced.
