Both? I simultaneously don’t give a fuck about most anything and hate everyone and everything.

A mix of both. I put up with less immaturity and am quickly becoming a "git off my lawn" type for people doing dangerous or disruptive things that they ought to know better than to be doing. At the same time I've gotten more patient in dealing with genuine mistakes and with people who lack knowledge or experience. Young kids, other adults, and most coworkers like me better now and I've been asked to take on a couple of mentoring roles. Teenagers and early 20s people in my neighborhood are starting to avoid me.

Yes

Some of both columns if I think about it. You go though enough that the volume on trivial crap gets turned way down and you don't sweat so many of the things you really can't affect substantively. While at the same time you're likely to be dismissive and not wish to waste time on folks that have demonstrated they're willfully ignorant dillweeds.

Depends on where I am at. In traffic (or just watching people drive cars around)? More grumpy. Stressful situations at work? More calm and laid back.

I don’t think my grumpiness level has particularly changed since I emerged from my grumpy teenage phase.

Yeah, bit of both. Overall way more laid back, especially when it comes to driving and generally dealing with the masses (shopping centres, events, etc.)

People are people and are only going to learn their lessons as they either see healthy examples before them or make their mistakes and follow up with the correct (and reflected) response.

Me getting pissed off isn't going to change anything.

However when there is a deliberate and selfish act in front of me I'll call that out. No problem.

Hopefully my teeny weenie physical sphere of influence will be enough.

I'm very laid back, but I'm bipolar too so that only goes so far. I get stressed by people around me getting stressed and in turn getting grumpy with me. It's hard to gauge how different that is to before I turned 30 but I feel less grumpy in myself.

I was born an "old man" really feel like I'm finally growing into my true phase of life. So not really any grumpier I would say.

I've developed a real interest in reading about cognitive science and psychology, and I really feel like that's made me more relaxed in accepting how different peoples' ideas, opinions and lived experience is; and it has really made me get over judging people for thinking the "wrong" thing.

I think mostly I am turning less patient, at least towards people who don't deserve it. That said, I assume everyone deserves it, but the older I get the easier people lose my respect and tolerance

Kind of both? I'm becoming more cynical, but my cynicism does tend to be fairly predictive. I am getting better at taking it in stride, though, and I try to be more laid back.
