Thanks for your honest clarification.
I totally get your reaction, and I have similar reactions myself all the time.
Some wisdom I got from elsewhere which I'm still working to practice is to eat-your-projections. We notice how other people are complainers and blamers and they make excuses and don't take responsibility. So, we turn it around and ask, "how am I being a complainer and blamer?" And we might notice how we're complaining about the complainers. And best to find this self-reflection humorous. If we switch to blaming ourselves for complaining, we're still blaming and complaining. Ideally, we find some empathy as we realize now something about how the complainers feel, and we realize that we didn't stop to be really curious about what is going on in their experience.
I agree with you completely about the value of taking responsibility. It's SO SO hard (I'm speaking for myself here!) to turn that around and literally ask, "what am I doing to take responsibility for this situation?" I.e. the situation in which other people were complaining, and their complaining triggered you, and you're unconsciously blaming them for your annoyed feelings instead of taking responsibility for your failure to be stoic.
Sorry for all the meta, this is stuff I am practicing, and it really seems the only "out" to the pattern. And really, take everything I just wrote as me noticing your patterns because I have them myself. I'm working on leading by example before telling you what you "should" do ("shoulding you" in one way to say it).
I'm laughing about this and about myself here, so I hope somehow that comes across in this overlong plain-text which I should expect to be misunderstood if I take my own damn advice. Haha ;)
