And that, of course, led me to thinking about it as a more general concept. I find that I tend to think less of the people I know when they make what I consider to be a bad choice, and I'm not sure I'm happy with that habit. On the other hand, I can't see being satisfied with my opinions on things shifting every time a friend does something I think is doofy.
And then, of course, there are things that people do that are doofy but don't really strike me as Bad Decisions, for whatever reason.
So I think I'm feeling that I know I'm good friends with someone when s/he can do something that triggers that in me, but my overall impression of hir is still positive, liking, and overall one of respect.
I appreciate peoples' thoughts on this, though, and I'm mulling over comments to respond over the weekend, I hope :)
